Heparan sulfate and cell division
(Associação Brasileira de Divulgação Científica, 1999-05-01)
Heparan sulfate is a component of vertebrate and invertebrate tissues which appears during the cytodifferentiation stage of embryonic development. Its structure varies according to the tissue and species of origin and is ...
Cell kinetics, stomatal differentiation, and diurnal rhythm in Allium cepa
Cell kinetics parameters were obtained for the three mitotic divisions leading to formation of stomata in the epidermis of the cotyledon of Allium cepa seedlings. Analysis of mitotic frequencies throughout the course of ...
Small GTPases as regulators of cell division
(Landes Bioscience, 2013-09)
The superfamily of small GTPases serves as a signal transducer to regulate a diverse array of cellular functions. The members of this superfamily are structurally and functionally classified into at least 5 groups (Ras, ...
Combination of sequences of cell Divisions in the anther wall formation in Solanaceae species
(Elsevier Gmbh, 2003-05)
Anther wall formation was studied in six Solanaceae species (Bouchetia anomala, Capsicum tovari, Margaranthus solanaceus, Physalis viscosa, Withania adpressa, and Withania riebeckii). Combinations of at least three different ...
In vitro assessment of the cytotoxic, apoptotic, and mutagenic potentials of Isatin
Isatin (1H-indole-2,3-dione) is a chemical found in various medicinal plant species and responsible for a broad spectrum of pharmacological and biological properties that may be beneficial to human health, as an anticonvulsant, ...
Sonic hedgehog signaling regulates mode of cell division of early cerebral cortex progenitors and increases
The morphogen Sonic Hedgehog (SHH) plays a critical role in the development of different tissues. In the central nervous system, SHH is well known to contribute to the patterning of the spinal cord and separation of the ...
