In turn, the plant cell wall has a complex carbohydrate composition, which is subjected to constant changes in the course of plant development. In this regard, proteins with lectin domains are of great interest in the context of studying their contribution to the tuning and moni...
During the past year, there have been rapid advances in our understanding of the early events of T-cell development, at the molecular level. Studies at the transcriptional level of T-cell receptor gene regulation have started to yield important clues about how different T-cell-specific genes can...

From beginning as a one-cell structure to your birth, your prenatal development occurred in an orderly and delicate sequence. There are three stages of prenatal development: germinal, embryonic, and fetal. Let’s take a look at what happens to the developing baby in each of these stages. ...
Immortalization of pituitary cells at discrete stages of development by directed oncogenesis in transgenic mice Targeted expression of oncogenes in transgenic mice can immortalize specific cell types to serve as valuable cultured model systems. Utilizing promoter reg... ET Alarid,JJ Windle,DB Whyte,....
The environment within a cell is a paradoxical balance of order and chaos. Proteins, DNA and countless other biological molecules tumble together in a wildly turbulent system that somehow holds together to engender life.
The descendants of the first cell to divide at the four-cell stage included, at both the fourth and fifth division, the first cell to divide and the cell with the shortest cell cycle time and had the shortest average cell cycle time at each division. The descendants of the cell opposite ...
Preceding chapters have mainly described various methods for sampling the different developmental stages and age groups of Mosquito populations. This chapter is concerned with analysing the numerical changes that occur in population size during the life-
SEPARATION OF STAGES IN THE DEVELOPMENT OF THE "T" CELLS INVOLVED IN CELL-MEDIATED IMMUNITY 喜欢 0 阅读量: 33 作者: Shortman,K.摘要: Density distribution analysis in continuous gradients of albumin has been used to study the development of cytotoxic lymphocytes (CL), to separate and ...
Sexually dimorphic development of the gonad is essential for germ cell development and sexual reproduction. We have found that the Drosophila embryonic gonad is already sexually dimorphic at the time of initial gonad formation. Male-spec... TJ Defalco,G Verney,AB Jenkins,... - 《Developmental C...
