Clones of telomerized fibroblasts of adult human skin have earlier been obtained. It was shown that despite their fast growth in mass cultures, these cells poorly form colonies. Conditioned medium, antioxidants, and reduced partial oxygen pressure enhanced their colony formation, but not to the level characteristic of the initial cells. The conditioned medium of telomerized cells enhanced colony f...... hiện toàn bộ
Age variability of the sexual size dimorphism in sables in nature and captivityRussian Journal of Developmental Biology - Tập 43 - Trang 232-243 - 2012
V. G. Monakhov
Inter-sexual differences in craniometric parameters were studied in sables of varying sex and age in natural (n = 2338) and farm (n = 516) populations. In nature, the differences between the skull size in males and females are, as a rule, highly significant (p < 0.001) and the size dynamics correlate well with age. In the farm population, the difference in the skull size between the sexes is stati...... hiện toàn bộ
Articulata and EcdysozoaRussian Journal of Developmental Biology - Tập 46 - Trang 121-126 - 2015

Science has accumulated to date such amounts of valuable and diverse information that no scientists can be encyclopedists (like those of the 17th and 18th centuries). Now every scientist is usually well informed only in one particular area and often needs consultations of other specialists. The current situation in biology is similar. In addition to evolutionary morphology, which represents fundam...... hiện toàn bộ
Some Paradoxical Phenomena in Hair Follicle HistophysiologyRussian Journal of Developmental Biology - Tập 52 - Trang 9-15 - 2021

The study was focused on the morphological features of the hair follicle and hair shaft of coarse-haired sheep. The results allow for explaining the paradoxical phenomenon of combining strong hair fastening in the skin with its continuous advancement towards the skin surface during hair growth. It has been shown that tooth-like structures of the hair cuticle’s surface and complementary indentation...... hiện toàn bộ
Age-Related and Individual Anatomical Variation in Testicular Topography in Human FetusesRussian Journal of Developmental Biology - Tập 49 - Trang 234-239 - 2018

At present, male infertility remains an urgent medical concern. From year to year, despite advances in methods of diagnosis and treatment, medicine encounters an increasing number of infertile couples with male infertility playing a leading role. Prerequisites for fertility disorders very frequently appear in childhood. Urologists consider cryptorchidism a leading cause of male infertility. The ai...... hiện toàn bộ
Comparative characteristics of new human embryonic stem cell lines SC5, SC6, SC7, and SC3aRussian Journal of Developmental Biology - Tập 42 - Trang 212-225 - 2011
A. M. Kol’tsova, O. F. Gordeeva, T. A. Krylova, N. V. Lifantseva, A. S. Musorina, T. K. Yakovleva, G. G. Poljanskaya
Numerous human embryonic stem cell lines with different genetic background are widely used as cell models for fundamental, biomedical, and pharmacological research. New hES cell lines SC5, SC6, SC7, and SC3a are derived from the blastocysts and maintained on mitotically inactivated human feeder cells. All derived hES cell lines passed through more than 120 cell population doublings, retained norma...... hiện toàn bộ
