November 1959 in “Annals of the New York Academy of Sciences” This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.
This research explores the use of serial block-face scanning electron microscopy to model the complex architecture of sheep wool fibres, focusing on the role and distribution of para- and ortho-cortical cells in determining wool curliness, though the mechanism remains unclear.
