HUMAN KERATINOCYTE CONDITIONED MEDIA.

Valuable CAS - / SKIN CONDITIONING

Human Keratinocyte Conditioned Media (KCM) is a potent biological extract containing a complex array of growth factors and signaling molecules. Sourced from cultured human keratinocytes, it is designed to intensely stimulate cellular regeneration and repair processes within the skin.

Anti-aging Skin Regenerative Cell Proliferation Stimulant Wound Healing Support Collagen Remodeling

Science

Mechanism of Action

KCM functions as a sophisticated 'Growth Factor Cocktail,' delivering a diverse blend of growth factors, cytokines, and soluble matrix proteins. These biomolecules act as critical cell signaling agents, orchestrating processes like cell growth, proliferation, differentiation, and tissue healing. Specifically, KCM promotes the re-epithelialization of compromised skin and enhances the expression of key type IV collagenases (72 and 92 kDa) in keratinocytes and fibroblasts, which are vital for basement membrane remodeling during repair. It also influences collagen regulation in dermal fibroblasts, notably reducing type I collagen mRNA and protein levels through keratinocyte-derived collagen-inhibitory factors (KD-CIFs).

Key findings

  1. 01 KCM significantly enhances cell proliferation in various human cell types, including fibroblasts, endothelial cells, keratinocytes, and smooth muscle cells.
  2. 02 It has been demonstrated to boost DNA synthesis in human fibroblasts by over 400%.
  3. 03 KCM is more potent than established growth factors like PDGF, EGF/TGF-alpha, and bFGF in stimulating diverse cell populations, without relying on EGF receptor activation.
  4. 04 It increases the presence of 72 and 92 kDa type IV collagenases in human keratinocytes and 72 kDa collagenase in human fibroblasts, crucial for effective basement membrane restructuring during healing.

Stability

While specific collagen-inhibitory factors demonstrate stable activity at acidic pH (pH 2) and elevated temperature (56°C), the overall ingredient, being a complex protein mixture, is generally susceptible to extreme pH, high temperatures, and enzymatic degradation. For optimal preservation, short-term storage typically ranges from 2-8°C, with long-term storage recommended at -20°C.
