July 2000 in “PubMed” This study found no structural differences between in vitro and in vivo grown hair, with keratinization and organization of keratin being comparable in both settings.
6 citations
,
October 1988 in “Clinics in Dermatology” This article reviews gaps in our understanding of molecular events in hair follicle growth, focusing on keratin synthesis and protein oxidation, but reports no new findings.
