HUMAN AMNIOTIC MEMBRANE STEM CELL CONDITIONED MEDIA.

Valuable CAS - / HAIR CONDITIONING, NOT REPORTED, SKIN PROTECTING

Human Amniotic Membrane Stem Cell Conditioned Media (AMSC-CM) is a potent complex derived from stem cells found in the human amniotic membrane, rich in growth factors, cytokines, and exosomes. This ingredient supports skin regeneration, repair, and rejuvenation by promoting cellular processes crucial for youthful, healthy skin. It is recognized for its ability to stimulate tissue repair and mitigate signs of aging.

Summary

Cell-communicating ingredient Antioxidant Wound healing Anti-inflammatory Collagen booster Reepithelization Tissue regeneration

Science

Mechanism of Action

AMSC-CM operates through paracrine signaling, delivering a sophisticated blend of biomolecules that include growth factors, cytokines, and exosomes to skin cells. These elements work synergistically to enhance cell proliferation and migration in both keratinocytes and fibroblasts, which are vital for skin integrity and healing. The conditioned medium actively stimulates the synthesis of collagen-1 and collagen-3, crucial for skin elasticity and firmness, while also promoting angiogenesis for improved nutrient delivery. Additionally, it offers significant antioxidant protection by boosting natural enzyme activity and reducing reactive oxygen species, thereby safeguarding against oxidative stress and mitigating cellular senescence. Its immunomodulatory and anti-inflammatory properties further support tissue regeneration, reepithelization, and extracellular matrix deposition, contributing to overall skin revitalization and anti-aging benefits.

Key findings

  1. 01 Topical application of 3 mL of AMSC-CM, combined with sodium ascorbyl phosphate, was utilized as part of a comprehensive pre- and post-CO2 laser treatment regimen, alongside tretinoin and sunscreen, to enhance skin rejuvenation.
  2. 02 Exosome-rich conditioned medium (ERCM) from AMSCs significantly boosted HaCaT keratinocyte proliferation in vitro by up to 162% within 24 hours at concentrations ranging from 6–30 μL/mL, and provided protection against H2O2-induced cytotoxicity.
  3. 03 In a rat model of full-thickness skin excision, topical application of ERCM solution (4 × 10^9 exosome particles/100 μL) markedly accelerated wound closure, enhanced the deposition of collagen-1 and collagen-3, and promoted angiogenesis.
  4. 04 Human Amniotic Fluid Stem Cell Conditioned Medium (hAFSC-CM) significantly increased the proliferation of human dermal fibroblasts by 125.95% and HaCaT keratinocytes by 132.72% in vitro, while also facilitating cell migration.
  5. 05 hAFSC-CM demonstrated potential for photo-aging improvement by inhibiting MMP-1 expression and upregulating procollagen 1A expression in human dermal fibroblasts following UVA irradiation.

Dusting Analysis

Not commonly dusted

Due to its complex biological nature as a conditioned medium, this ingredient is not typically subject to 'dusting' concerns related to minimal percentage inclusion like some other cosmetic actives.

Stability

Optimal stability requires storage between 2-8°C for short durations (up to 72 hours) or -20°C for long-term preservation. Maintaining sterility and aseptic conditions during processing is crucial. The active protein and growth factor components are highly susceptible to degradation by extreme pH, elevated temperatures, and certain enzymes or harsh chemical agents.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

Neither the Cosmetic Ingredient Review (CIR) nor the Scientific Committee on Consumer Safety (SCCS) has evaluated this ingredient for cosmetic use. The U.S. FDA has increased regulatory oversight on amniotic fluid-derived products, classifying those with therapeutic claims (e.g., wound healing via injection) as drugs or biologics requiring premarket approval. The FDA has issued warning letters for unauthorized products. While the conditioned medium is generally free of live cells, its regulatory standing derived from biological source material is complex. Amnion-derived stem cells themselves have demonstrated low immunogenicity and absence of tumorigenicity.
