Glossary Hedgehog signaling pathway

regulates cell growth and development through protein-receptor interactions

The Hedgehog signaling pathway is a crucial mechanism in developmental biology that regulates cell growth, differentiation, and tissue patterning. It involves the Hedgehog proteins binding to receptors on cell surfaces, which then trigger a cascade of intracellular events that influence gene expression. This pathway is essential for proper embryonic development and, when dysregulated, can lead to conditions such as cancer and congenital disorders.

research Disruption of the hedgehog signaling pathway contributes to the hair follicle cycling deficiency in Vdr knockout mice

53 citations , May 2010 in “Journal of Cellular Physiology”

This study found that mice lacking the Vitamin D receptor showed disrupted hair follicle cycling, which was partially restored with hedgehog signaling pathway activation, suggesting a role for this pathway in follicle regulation independent of vitamin D.

research Exosomes Derived From Human Adipose-Derived Stem Cells Inhibit Lipogenesis Involving Hedgehog Signaling Pathway

13 citations , August 2021 in “Frontiers in Bioengineering and Biotechnology”

This study found that adipose-derived exosomes may inhibit adipogenesis and lipogenesis in adipose-derived stem cells by activating Hedgehog signaling, suggesting potential applications for improving wound healing in obesity.

community New study suggests hair regrowth on wounded and bald skin may be possible

4 upvotes 7 years ago

Hair regrowth on wounded and bald skin may be possible by activating the sonic hedgehog gene, leading to hair regrowth in mice. The findings are promising but may not directly apply to humans.

community Amplifica: Hope or Cope? A Review of Their Pipeline

9 upvotes 1 month ago

Amplifica's AMP-303 showed a modest increase in hair growth, but results were inconsistent and potentially misleading. Hyaluronic acid and osteopontin are being explored for hair growth, with varying effects on different hair types and conditions.

community SCUBE3 and GT20029 could be the closet thing to a cure: Hair Follicle Regeneration and Protection Against DHT

14 upvotes 3 years ago

SCUBE3 and GT20029 are potential treatments for hair loss, with SCUBE3 stimulating hair growth and GT20029 protecting against DHT. A combined approach using SCUBE3, finasteride or dutasteride, and later GT20029 could provide a comprehensive treatment for androgenetic alopecia.

community Most Promising Future Hair Loss Treatments In 2026

83 upvotes 1 week ago

Promising hair loss treatments in 2026 include GT20029, a topical androgen receptor degrader, and VDPHL01, an extended-release oral minoxidil, both offering safer alternatives with fewer side effects. Other treatments like sublingual minoxidil, OND-1, JW0061, TDM-105795, and AMP-303 are also being explored.
