    TLDR Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.
    The document reviewed the early stages of development for ectodermal appendages such as hair follicles, teeth, and mammary glands, focusing on the induction, placode, and bud stages. It summarized molecular and cellular processes identified through mouse mutant analysis and reevaluated classic epithelial–mesenchymal recombination experiments with current molecular insights. Emphasis was placed on signaling pathways mediating tissue interactions and their impact on cellular behavior shaping the developing organs.

      community Verteporfin and Microneedling

      in Treatments 5 months ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
