March 2026 in “Frontiers in Cell and Developmental Biology” This meta-analysis found that autologous cell-based therapies, especially stromal vascular fraction, significantly improved atrophic acne scars over control treatments, enhancing both clinical and patient-reported outcomes.
May 2026 in “International Journal of Molecular Sciences” This study found that plucked hair follicles can serve as a practical and scalable source for regenerative medicine, as researchers successfully isolated and expanded keratinocytes and mesenchymal stem cells for potential cell-based and cell-free therapies, demonstrating significant wound-healing bioactivity in vitro.
November 2022 in “Journal of Investigative Dermatology” This study found that autologous γdTregs displayed significant protective effects on alopecia areata-affected human scalp hair follicles in both ex vivo and in vivo settings, suggesting potential for future cell-based therapy.
September 2026 in “Wound Repair and Regeneration” This systematic review suggests that stem cell-based therapies may offer potential benefits for healing pure venous ulcers, but findings are preliminary due to small sample sizes and varied interventions.
February 2024 in “Plastic and Reconstructive Surgery – Global Open” This systematic review found that both cellular and acellular stem cell-based therapies are safe and able to improve hair regeneration and density in patients with androgenic alopecia, although some results may be temporary.
