Thymosin beta4 accelerates wound healing
Malinda KM, Sidhu GS, Mani H, et al. Journal of Investigative Dermatology 1999;113:364-368.
What it found
Full thymosin beta-4 increased skin regrowth over the wound by 42% at day 4 and up to 61% at day 7 compared with saline, with more contraction, collagen and new blood vessels. In a lab chamber it made keratinocytes migrate 2 to 3 times more.
Limitations
