CELLINK SKIN has fibrinogen to recreate the natural wound-healing environment found in skin tissue. It is optimized for culturing fibroblasts and keratinocytes to fabricate skin constructs. CELLINK SKIN comes with an enhanced thrombin-containing crosslinking solution to develop a compound network with unparalleled stability. After crosslinking with thrombin, CELLINK SKIN’s in situ fibrin and fibrinogen provides an environment that mimics the natural wound-healing process.

This product contains Nanofibrillated Cellulose, jointly patented by UPM-Kymmene Corporation and CELLINK AB.
