3 wrz 2019 · In the last century, human scalp hair morphology has been studied from multiple, and sometimes mutually exclusive, perspectives by anthropologists, biologists, geneticists, forensic scientists, and cosmetic scientists. Here, we review and synthesize historical and current research on hair to better understand the scientific basis and biological ...
Here, we review and synthesize historical and current research on hair to better understand the scientific basis and biological implications of hair microstructure and morphology.
3 wrz 2019 · This study establishes trait patterns in hair morphology and ultrastructure among three biogeographically defined metapopulations to improve the current understanding of human variation in...
Classically, distinct stages of hair follicle morphogenesis have been defined, in the mouse model, based on 1) changes in cell morphology and aggregation, 2) expression of few known molecular markers, 3) the extent of follicle downgrowth, and 4) the presence of differentiating cell types.
This chapter is concerned with the structure of the mature human hair shaft and the chemical composition of its subcomponents as adduced from the examination of fibres mainly with the conventional transmission electron microscope (TEM).
14 paź 2019 · From the combined microscopic and DSC evidence, we suggest that two, non-homogeneous, major cell groups occur consistently in all keratin fibres, including human hair. 14 We refer to these as ortho- and para-type cells, using established notation.
8 gru 2007 · To identify hair morphology-determining genes, the levels of local genetic differentiation in 170 genes that are related to hair morphogenesis were evaluated by using data from the International HapMap project.
