If you have searched "what are stem cells," you may have encountered both promising science and bold treatment claims. Stem cells are unspecialized cells that can renew themselves and, under certain conditions, develop into more specialized cell types. That biology is important, but it does not mean every stem cell product is an established treatment or that the same claims apply to every cell source.
This guide explains the basics in plain language: how stem cells differ from other cells, the main types researchers discuss, and where cells may come from. It also outlines what Atlanta patients can ask when evaluating treatment information. The goal is to help you separate a scientific concept from a claim about a specific product or procedure. So you can have a clearer conversation with a qualified clinician.
Stem cell research spans many areas, while established medical uses, regulatory status, and evidence vary by product and intended use. A careful discussion should identify exactly what is being offered, what is known about that use, and what questions remain. The sections below begin with the basic definition, then move from cell types and sources to informed decision-making.

What Are Stem Cells and How Do They Work?
Stem cells are unspecialized cells that can make more stem cells and can develop into one or more specialized cell types. NIH explains these abilities as self-renewal and differentiation. A blood cell, muscle cell, or nerve cell has a more specific job. A stem cell has the potential to renew itself or produce a cell that becomes more specialized.
One way to picture this is a branching path. A stem cell can make a copy of itself, or it may produce a cell that begins to take on a particular role. The process is not a simple switch that works the same way for every cell. The cell's type and environment matter, and different categories of stem cells have different ranges of potential.
In the body, some tissue-specific stem cells contribute to maintaining the tissue where they are found. For example, blood-forming stem cells can produce cells in the blood system. In research, scientists study how stem cells develop, how cells become specialized, and whether particular cell types may have future medical uses. These research questions are distinct from evidence about a particular treatment offered to patients.
Self-renewal and differentiation are different abilities
Self-renewal means that a stem cell can divide and produce more stem cells. Differentiation means that a cell develops characteristics of a more specialized type. Depending on the cell category, the range of possible specialized cells may be broad or limited. Many adult stem cells are associated with particular tissues rather than being able to become any cell in the body.
Those basic properties help explain why stem cells are studied. They do not, by themselves, show that a product can restore a particular tissue, relieve symptoms, or treat a specific condition. A treatment claim needs evidence for the specific product, route, and intended use. The term "stem cells" describes a broad biological category, not a single interchangeable therapy.
Why does this distinction matter to patients?
When a website or advertisement describes stem cells, consider whether it is discussing cell biology, laboratory research, or a treatment being offered to people. Each is a different kind of statement. A scientific description of what some stem cells can do under certain conditions is not a promise about what a procedure will do for an individual patient.
That distinction is especially useful when comparing options or preparing questions for a healthcare professional. Ask what specific product is involved, what evidence supports its intended use, and what uncertainties remain. Next, it helps to understand that the word stem cell covers several different cell types.
What Types of Stem Cells Are There?
Stem cells are often grouped by their source and by the range of cells they may become. Some types are mainly studied in laboratories; others have roles in the body's tissues or in specific medical contexts. The categories below are a simplified overview, not a list of interchangeable products or treatments.
| Type | Source |
|---|---|
| Embryonic | Embryos |
| Induced pluripotent | Reprogrammed cells |
| Adult or tissue-specific | Some tissues |
| Blood-forming | Blood or marrow |
Pluripotent cells and tissue-specific cells
Some stem cells can become many cell types. Scientists call this pluripotency. Induced pluripotent cells start as mature cells. Researchers reprogram them in a laboratory.
Adult, or somatic, stem cells are different. They occur in tissues and are generally linked to specialized cells in those tissues. Blood-forming stem cells can give rise to cells in the blood system. So the label "stem cell" does not mean every cell type has the same source, behavior, or use.
A type of cell is not proof of a treatment result
Names such as embryonic, induced pluripotent, adult, or blood-forming describe biological categories. They do not tell a patient whether a particular product is appropriate, authorized, or supported for a specific use. Context matters, including how a product is sourced and handled, how it is intended to be used, and what evidence exists for that use.
For example, research into a cell type may explore future possibilities, while an established medical use may be limited to a specific product and indication. Those facts should not be blended into a broad claim that stem cells treat many conditions. Understanding the categories makes it easier to ask precise questions about source and intended use, which we explore next.
Where Do Stem Cells Come From?
Stem cells occur in different biological settings. Tissue-specific stem cells have been identified in a range of organs and tissues, where they are associated with the specialized cells of that tissue. Blood-forming stem cells are found in blood and bone marrow, and they are also present in certain umbilical-cord-blood products used in specific medical contexts. Embryonic stem cells and induced pluripotent stem cells are discussed largely in the context of laboratory research.
There is no single source that applies to every stem cell type. The source, processing, and intended use all matter. A broad phrase such as "stem cell treatment" may refer to products that differ substantially. So patients should ask what exact product is being discussed rather than assuming two offerings are comparable because they share a name.
How the clinic describes its biologic materials
Preferred Regen ATL describes its stem cell service as using biologic-derived products obtained from reputable, compliant laboratories, with umbilical-cord sourcing. This is the clinic's description of its offering; it is not a claim that source alone establishes safety, effectiveness, or suitability for an individual. The clinic's stem cell service information provides more detail about that specific service.
It is also useful to keep different regenerative approaches distinct. For example, the clinic's guidance describes platelet-rich plasma (PRP) as prepared from biologics or from a patient's own blood processed in-office to concentrate platelets and growth factors. That is separate from the clinic's stem cell and exosome wording, which describes biologic-derived products from laboratories. A patient should ask which material is being offered and how the clinic describes it.
Questions to ask about source
During a conversation with a clinician, you can ask what type of cells or biologic product is involved. Where it comes from, and how it is handled before use. You can also ask what the product is intended to do, what evidence supports that use, and what is not yet known. Clear answers help you distinguish basic information about cell sources from claims about clinical outcomes.
Learning a product's source is only one part of evaluating a treatment claim. The next step is to understand the evidence, regulatory status, risks, and alternatives for the exact intended use.
What Should Atlanta Patients Know About Stem Cell Treatment Claims?
Stem cell biology, laboratory research, and a treatment offered to a patient are not the same thing. A study may examine whether a cell type could be useful in the future. But that does not establish that a specific product is approved or effective for a condition today. For patients in Atlanta or elsewhere, a claim should be tied to the exact product, intended use, and evidence behind it.
The FDA regulates regenerative medicine products, including stem cell products. Its consumer alert on regenerative medicine products states that the only FDA-approved stem cell products for use in the United States are blood-forming cells derived from umbilical cord blood for disorders affecting blood production. The alert also says these products are not approved for other uses. And that stem cell products have not been approved for orthopedic conditions such as osteoarthritis, back pain, or knee pain. This is an important distinction when reading broad claims online.
Regulatory status is one question to ask, not a substitute for an individual medical discussion. Ask what product is being offered, what it is intended to do. What evidence supports that particular use, what risks and uncertainties have been identified, and what alternatives may be appropriate. You can also ask what follow-up is recommended and what costs or practical considerations apply before deciding.
A thoughtful consultation starts with your circumstances
A responsible discussion should make room for your health history, goals, questions, and other options. Preferred Regen ATL describes its care process as consultation and assessment before an individualized plan. That does not mean every person is a candidate or that a particular outcome can be predicted. It means a clinician can discuss the specific service, the information available, and whether further evaluation is appropriate for your situation.
If you want to ask about how cell products are sourced and what evidence applies to a specific use, contact the clinic to discuss your questions.

Frequently Asked Questions
What do stem cells do?
Stem cells can renew themselves and may develop into more specialized cell types. In the body, certain tissue-specific stem cells contribute to maintaining the tissues where they are found. These biological abilities do not guarantee that a particular stem cell product will treat a condition.
Where are stem cells found?
Stem cells have been identified in a range of tissues and organs. Blood-forming stem cells are associated with blood and bone marrow, and certain blood-forming products come from umbilical cord blood. Different sources and cell types have different properties and uses.
Why are stem cells controversial?
Discussion can involve different cell sources, research, ethical questions, and claims about treatments. The FDA cautions consumers about misleading claims for regenerative products. It is helpful to distinguish an area of active research from a product approved or supported for a specific use.
What is a risk of using stem cells?
Risks depend on the specific product, how it is prepared and used, and the patient's circumstances. The FDA warns that some unapproved regenerative products may pose safety concerns. Ask a qualified clinician about known risks, uncertainties, alternatives, and whether the product is authorized for its intended use.
Can stem cells cure diseases?
There is no single answer for all stem cells or diseases. Some specific blood-forming stem cell products are approved for certain blood disorders, while many other potential applications remain under study or are not approved. Do not assume a general claim about stem cells applies to a specific condition or treatment.
Talk With a Clinician About Your Questions
Learning what stem cells are can be a useful starting point, but a decision about treatment involves more than cell biology. If you are in Atlanta and considering a regenerative medicine service, ask about the specific product. The intended use, the available evidence, and the risks or uncertainties relevant to your circumstances. A conversation can help clarify what an assessment may involve without assuming that a particular option is right for everyone.
