February 1992 in “Development” This study characterizes a type II keratin intermediate filament gene family involved in early sheep follicle differentiation, detailing gene expression patterns and sequences in hair cortical cells.
98 citations
,
December 1991 in “Annals of the New York Academy of Sciences” This study found that conserved DNA motifs and expression patterns in keratin genes suggest functional regulatory similarities in hair follicle differentiation across different mammalian species.
68 citations
,
December 1991 in “Annals of the New York Academy of Sciences” Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.
