The interphase nucleus of the cells of several tissues of Lacandonia schismatica was studied using electron microscopy cytochemical and immunocytochemical methods. The EDTA staining procedure, preferential for RNP, contrasted ...

Background information. Germination is a well-characterized process in which embryo cells of seeds experience a programmed transition from quiescence to proliferation. For this reason they constitute a very good system to ...

The synaptonemal complex (SC) is the central key structure for meiosis in organisms undergoing sexual reproduction. During meiotic prophase I, homologous chromosomes exchange genetic information at the time they are attached ...

By light and electron microscope cytochemistry we characterized the interphase nucleus of Lacandonia schismatica, the only known species of the new plant family Lacandoniaceae, whose most peculiar feature is the inverted ...

One of the most constant and typical histological markers of thyroid papillary carcinoma is the presence of multilobated and ground-glass nuclei. With the intention of extending and characterizing the ultrastructural ...
