    TLDR Engineered skin using stem cells and collagen sponge effectively healed and regenerated complex skin features in mice.
    The study demonstrated that tissue-engineered skin using ES cell-derived epidermal stem cells and collagen sponge effectively restored full thickness skin defects in mice. The engineered skin healed the defects within 3 weeks, resulting in thicker than normal skin with an increased basal layer. The epidermis showed expression of β1 integrin, CK15, and CK19, while the dermis exhibited structures expressing β1 integrin and CEA. After 4 weeks, the newborn skin developed sebaceous glands-like and hair follicles-like structures, indicating successful regeneration of complex skin features.

It also stresses the importance of patience when using these treatments.

      A 32-year-old man has been treating his hair loss with daily oral finasteride (1.25g), twice-daily topical minoxidil, weekly ketoconazole 2% shampoo, and weekly microneedling for almost three months, with no side effects from finasteride. He started with a Hamilton Norwood scale rating of 5 and has seen improvement without experiencing pain by using a 0.8mm needle length for microneedling.
