STUDIES ON ORGANOGENESIS

Studies on Organogenesis

1. Isolated blood cells, when placed for incubation in a plasma substratum, are capable of constructing highly organized, tubular processes that project from the explanted cell mass into the surrounding medium. 2. The tubular structures have fibrillar walls that may be covered, eventually, by a membranous layer of leukocytes. Their lumina contain blood cells suspended in fluid. 3. The formation...

Studies on the Effect of Genotype and Explant Type on Callogenesis and Organogenesis in Indica Rice

The purpose of the research study is to select the best rice explant and variety for Agrobacterium mediated genetic transformation studies. In vitro callus induction and regeneration frequency of two explants i.e. immature embryo and mature grains of 9 rice varieties (Oryza sativa L.) was investigated by culturing explants source on N6 media supplemented with 2, 4-D at 2mg/l for callus inductio...

Organogenesis: Drosophila goes gonadal

In many animals, germ cells migrate to the gonad to assemble into a functional organ. Recent work in Drosophila has built a picture of the gene activities that specify the gonad and allow it to attract germ cells, and has led to the identification of a gene, columbus, that may encode the attractive factor.

Stages of Kidney Organogenesis

temporal coordination of numerous biomolecular interactions. Approaches geared toward elucidating the molecular and cellular basis of kidney development and branching morphogenesis have focused on the study of discrete molecules and signaling pathways by using genetic and in vitro approaches (reviewed in Refs. 11 and 71), more recently combined with microarray studies (66, 74, 75). To date, int...
