What it is

DayZero AF Exosomes 500B is an amniotic fluid-derived extracellular vesicle preparation manufactured by ZEO ScientifiX, Inc., a Florida-based regenerative biologics company. The label designation "500B" refers to the particle count stated on the vial — a neutral manufacturing specification, not a clinical dosing recommendation. The preparation is classified as extracellular vesicles (EVs), a category studied for their role in cellular communication.

Source & manufacturing

This material is derived from amniotic fluid, a perinatal tissue source. ZEO ScientifiX holds patents on perinatal-fluid processing techniques and is an SEC-registered public company with an active clinical research portfolio. TC Regen sources this material from ZEO ScientifiX as a documented supplier.


How TC Regen uses it

At TC Regen Naples and TC Regen Fort Myers, DayZero AF Exosomes 500B is administered only under the direct supervision of a licensed physician. Inclusion in a treatment plan is diagnosis-driven — a physician evaluates each patient individually and determines whether this material is appropriate for their specific condition. No two plans are identical.

Regulatory status

This product is not FDA-approved. No FDA-approved exosome products currently exist for any human therapeutic use. The FDA classifies exosome preparations as unapproved biologics under Section 351 of the Public Health Service Act. TC Regen administers this material in compliance with Florida's Stem Cell Therapy Act, which requires written informed consent and explicit disclosure that the therapy is not FDA-approved. Patients receive that disclosure before any administration.

Can stem cell therapy help knee pain without surgery?

Stem cell therapy may help some patients manage knee osteoarthritis pain and potentially delay or avoid knee replacement, though results vary by individual and the therapy is not FDA-approved. At TC Regen in Naples and Fort Myers, a physician evaluates the knee with imaging to determine whether a regenerative injection is appropriate or whether surgery is the better option.

Is stem cell therapy or knee replacement the better option?

Is stem cell therapy or knee replacement the better option?

Knee replacement is an established surgical option for severe arthritis, while regenerative injections such as stem cell therapy or PRGF may be considered for moderate joint damage when patients want to delay or avoid surgery. TC Regen physicians in Southwest Florida weigh the stage of arthritis, imaging, and patient goals to advise which path fits, since regenerative treatment is not right for every diagnosis and is not FDA-approved.

How much does stem cell therapy cost, and does insurance cover it?

How much does stem cell therapy cost, and does insurance cover it?

Stem cell and other regenerative therapies are generally not covered by insurance because most are not FDA-approved, and out-of-pocket cost depends on the joint treated and the specific therapy. TC Regen reviews pricing during a consultation at its Naples or Fort Myers locations rather than listing prices online.

What is the difference between stem cells, PRP, and exosomes?

What is the difference between stem cells, PRP, and exosomes?

Platelet-rich growth factor (PRGF) concentrates healing factors from a patient's own blood, mesenchymal stem cells are cellular products that may support the body's repair response, and exosomes are cell-derived signaling particles being studied for tissue healing. At TC Regen, a physician selects among these based on the structural diagnosis; stem cell and exosome therapies are not FDA-approved.

Is stem cell therapy safe, and what are the side effects?

Is stem cell therapy safe, and what are the side effects?

Studies suggest side effects from regenerative injections are typically minor, most often temporary soreness or swelling at the injection site, though any procedure that breaks the skin carries some risk of bleeding or infection. TC Regen performs injections under image guidance using cells from AABB-accredited sources and reviews individual risks during the written informed-consent process required by Florida law.

Can regenerative medicine treat hip, shoulder, or back pain?

Can regenerative medicine treat hip, shoulder, or back pain?

Regenerative treatments may be considered for orthopedic conditions beyond the knee, including hip osteoarthritis, rotator cuff and shoulder injuries, and chronic low back pain. TC Regen in Naples and Fort Myers evaluates each case individually, since regenerative therapy is not appropriate for every condition and stem cell therapy is not FDA-approved.
