The Development of Hair Follicles in the Marsupial Trichosurus Vulpecula

Abstract

The development of hair follicl'3s in the brush-tailed possum T. vulpecula has been studied in skin samples from animals ranging in age from embryos to adults. The first follicles appear at about 2 days after birth and develop rapidly, producing minute non-medullated hairs (about 0·5 mm long) during the first hair cycle.
