After RNA extraction from horsehair shafts and roots, the mRNAs of β-actin, muscle-type phosphofructokinase, and transforming growth factor-β1 were detected by reverse transcription polymerase chain reaction assay. Low amounts of RNA were present in the horsehair. These specific mRNA transcripts were readily detected when more than three hair roots were used. However, detection of the mRNA tran...
were scalped when their hair became entangled around the inadequately guarded rotating drivelines or shaft of farm machinery driven by power takeoffs (PTOs).

In the present study, we show that estrogen induced apoptosis of precortex cells and caused pre...
Melanocyte regeneration in epidermis (e.g., vitiligo) and matrix of hair follicle graying hair) is quite dependent on the migration melanocyte precursors located follicle. We have demonstrated that casein kinase (CK) 1 ablation keratinocytes increases eumelanin production epidermal numbers. Here we further evaluate effect CK1 inhibition first established Fusion Red-labelled-melanocyte reporter ...
