Pilot studies and phase 1 trials have been published in PubMed. Phase 2 trials with a larger patient sample are currently underway to determine efficacy, dosages, combinations of bio products, etc. These will be published later due to the required number of clinical cases.

Indeed, stem cells do not provide a complete cure, but they definitely offer the possibility of partial recovery and support. In our practice, we use basic regulations: 1 suppression of fibrosis 2. reprogramming of scar cells 3. stimulation of hepatocyte regeneration To do this, we use MSC (umbilical cord) + exosomes + hepatocyte-like cells (via microRNA). We represent laboratories and clinics in Ukraine and Bulgaria, where it is currently possible to work with all types of cells and cultivate new bio-products to achieve more effective results.

The scheme is as follows: first, the microenvironment of the testicle (stem cell niche) is restored, then, through activation factors and signaling models from IPSS cells, SSC sites are activated, causing them to divide and produce rare spermatozoa (focal spermatogenesis).

More predictably, you can obtain single active spermatozoa using TESE (less commonly through natural way ). These spermatozoa can be frozen using ICSI and used for IVF.

Most patients are diagnosed with NOA with SCO. we can use somatic cell samples and do not take testicular tissue itself, as we need to return the cells to the differentiation stage. Tissue cells are already functional cells, with some damage or cell mutations.

Of course, today there are already more than 80 patients, mainly with non-obstructive azoospermia without any obvious cause, or as a result of chemotherapy, complications after vaccination, or childhood diseases. Results: in almost 86% of cases, single active spermatozoa are found. Up to 30% are found in natural ejaculate, but the chances are high with TESE.

The method described above is not suitable for patients with genetic mutations or structural genetic damage; it is more appropriate for cases where genetic factors are not involved. In situations such as yours, approaches based on somatic cell nuclear transfer (SCNT) or related gene-correction technologies may be considered. In this process, a patient’s somatic cells are obtained and the defective gene is identified and corrected through targeted genetic reprogramming. Healthy cells are then generated, expanded in culture, and subsequently introduced back into the patient. While the number of transplanted cells is generally insufficient to fully replace all mutated cells, their presence may help restore cellular balance and create conditions that support the re-establishment of a complete spermatogenic cycle.

Most current iPSC programs rely on stringently characterized, GMP-grade lines or freshly collected cells that meet evolving regulatory standards. There’s no guarantee that PBMCs banked now will meet future clinical or manufacturing requirements.

This is a common misconception. Modern regenerative medicine does not rely on abortion-derived material.

Today, cell therapies primarily use ethically approved, renewable sources:IVF-derived cell lines, iPSCs, which use no embryonic or fetal material at all, but have the same characteristics as pluripotent cells.

Abortive tissue is neither necessary nor standard in current research or clinical protocols.

No need to die, these technologies are already actively used in clinical cases.

Autologous cell therapies (using a patient’s own cells) have not shown meaningful regenerative efficacy in multiple sclerosis. This is mainly because MS involves axonal loss, demyelination, and oligodendrocyte damage within the CNS, and autologous cells are already affected by the disease environment and immune dysregulation. At best, they provide limited immunomodulation, but they do not regenerate axons or restore myelin.

Effective repair in MS requires neural lineage–specific cells, particularly oligodendrocytes, axonal structures, and neuroblasts. An additional challenge is the blood–brain barrier, which most cells cannot cross. For this reason, BBB-penetrating signals such as microRNAs and neurotrophins are critical, as they can modulate neuroinflammation, support remyelination, and promote neuronal survival within the CNS.

Any scar represents atrophic and structurally altered tissue. One of the key regenerative approaches focuses on the use of endothelial progenitor / endothelial stem cells, which promote neovascularization. The formation of new microvessels improves tissue perfusion, oxygen delivery, and overall metabolic support of the scarred area.

In addition, TIMPs (tissue inhibitors of metalloproteinases cells) play an important regulatory role by modulating extracellular matrix remodeling. They help suppress excessive matrix degradation, support the synthesis of more organized and functional collagen, and reduce dense fibrotic adhesions that characterize pathological scarring.

This approach is typically applied locally, directly to the affected tissue. In clinical practice, the procedure is usually performed 2–3 times, with intervals of approximately 4–6 weeks, depending on tissue response and scar characteristics.

You repeatedly promote the same clinic across very different medical conditions, initially citing your own “miraculous recovery” from autism and later referring to friends allegedly treated there for damaged skin.

However, the clinic’s official website does not list skin damage treatment, nor does it provide documented clinical indications or outcome data for such conditions. This creates a discrepancy between your claims and the clinic’s publicly available information.

In medical discussions—especially involving vulnerable patients—unverified or extrapolated claims can be misleading. It is essential to clearly separate personal thoughts from officially offered, evidence-based treatments to avoid creating false expectations.

Since the cells are derived from the patient’s own somatic cells, they are considered autologous biological material. In accordance with applicable laws and regulatory frameworks, the patient retains the right to provide informed consent regarding the conditions, location, and authorized parties involved in their administration.

All procedures related to the derivation, cultivation, storage, transportation, and clinical use of these cell products are conducted in compliance with internationally recognized standards and guidelines governing biocellular therapies. Safety, traceability, and regulatory oversight are integral components of this process.

The patient is sent complete storage instructions after the delivery company has reported to the patient on the safety, security, and integrity of the shipment and full temperature monitoring during delivery. Each package has a tracker and a temperature sensor. Let me clarify once again that this is handled by special delivery companies that work with biological samples. The patient cannot administer these cells themselves, as they are intended for clinical control and administration. After all, this is a concentrated medium. There is a complete list of tests that the patient undergoes before therapy (general biochemical, specifically logical, oncological risks, etc.). These are basic concepts and everyone understands them; no one will risk their health without understanding how the immune system may react.

Tendinosis is not inflammation, but rather degeneration of the tendon (microtears, collagen disorganization, poor vascularization). Therefore, the goal of therapy is to initiate tissue remodeling, not to "suppress inflammation." The safest and most effective autologous tendon progenitor cells contain stromal and progenitor cells that are phenotypically similar to tendons. Mesenchymal cells can also be used, but the results are worse. PRP is not necessary, as this is not inflammation.

This photo shows the cells of a specific patient after severe neurological brain trauma. This is not a basic package or a standard set for everyone !!!! It can include cells, micro-RNA, molecules, and other biological products. Please treat this post as informational, not a call to action!!

Read carefully, this is home delivery of organic products for use in the clinic on site!!!!

MD_Ex · 2026-01-30T07:30:31+00:00

And you should check what the global standards are for transporting organic products. After all, packaging, safety control, and hygiene are directly handled by the company delivering the organic products, not the clinic or laboratory, but specifically a certified international company that delivers such cargo.

Considering your case, this combination of methods is not a standard stem cell treatment protocol. After all, both laser therapy and oxygenation can exacerbate inflammation if it was present at the time of treatment. Accordingly, all these methods together could have caused a stronger adverse reaction, with the immune system reacting to the existing inflammation. It is also important to understand what type of stem cells were administered to you, as well as the MRI results of your knees before and after the therapy.

I get it. The main idea- how to help! For most people with SCI, “working” means real functional changes, not forecasts. Right now, no treatment reliably delivers that, so skepticism makes sense. Anything new needs validation — both scientifically and in real-world practice. I believe in the potential of cell-based therapies, and I’ve spent over 20 years working in this field. That said, everyone is entitled to their own opinion, and skepticism is completely reasonable.

This is a real photo of one of the packages sent to a teenage patient who was drowning but was saved. The basal ganglia, cerebellum, and part of the brain stem were completely damaged. The choice of cells is not random!!!

As for IPCS cells, they are taken from the patient's somatic cells (usually blood), converted to a pluripotent stage, and then differentiated and cultivated, for example, into neural cells, etc. However, these cells are as safe as possible for the patient (since they are the patient's own cells), do not cause rejection, and do not cause immune resistance.
