Reproductive meristem fates in Gerbera.
Flowering plants go through several phases between regular stem growth and the actual production of flower parts. The stepwise conversion of vegetative into inflorescence and floral meristems is usually unidirectional, but under certain environmental or genetic conditions, meristems can revert to an earlier developmental identity. Vegetative meristems are typically indeterminate, producing orga...
متن کاملSpecifying pancreatic endocrine cell fates
Cell replacement therapy could represent an attractive alternative to insulin injections for the treatment of diabetes. However, this approach requires a thorough understanding of the molecular switches controlling the specification of the different pancreatic cell-types in vivo. These are derived from an apparently identical pool of cells originating from the early gut endoderm, which are succ...
متن کاملFATES: Finding A Time dEpendent Shortest path
We model a moving object as a sizable physical entity equipped with GPS, wireless communication capability, and a computer. Based on a grid model, we develop a distributed system, FATES, to manage data for moving objects in a two-dimensional space. The system is used to provide time-dependent shortest paths for moving objects. The performance study shows that FATES yields shorter average trip t...
متن کاملOrigins and Fates of Cardiovascular Progenitor Cells
Multipotent cardiac progenitor cells are found in the fetal and adult heart of many mammalian species including humans and form as intermediates during the differentiation of embryonic stem cells. Despite similar biological properties, the molecular identities of these different cardiac progenitor cell populations appear to be distinct. Elucidating the origins and lineage relationships of these...
متن کاملCD4 T cells: fates, functions, and faults.
In 1986, Mosmann and Coffman identified 2 subsets of activated CD4 T cells, Th1 and Th2 cells, which differed from each other in their pattern of cytokine production and their functions. Our understanding of the importance of the distinct differentiated forms of CD4 T cells and of the mechanisms through which they achieve their differentiated state has greatly expanded over the past 2 decades. ...
