The unique anatomical patterns of the brain that clearly separate stem cell niches as a potential pool of CSCs from differentiated tissue make the brain an ideal model system to study the impact of radiation dose given to these stem cell niches.
Besides estimating the number of compartments, our model allows us to estimate the size of each compartment, the rate of cell replication within each compartment, the mean time a given cell type contributes to hematopoiesis, the amplification rate in each compartment, as well as the mean time separating stem-cell replication and mature blood-cell formation.
Loop 1 spans the deep major groove of stem 2, and loop 3 spans the shallow minor groove of stem 1. Loop 2, which is usually zero or one nucleotide, separates stems 1 and 2. For the formation of a pseudoknot, the lengths of the other loops have to meet some requirements (24).
BOK CHOY WITH SHIITAKES Adapted from Charles Phan Time: 20 minutes 2 tablespoons neutral oil, like corn or canola 1 tablespoon minced garlic 4 to 6 heads baby bok choy, or 1/2 head large bok choy, leaves and stems separated and stems roughly chopped 10 small shiitake mushrooms, caps only, left whole 1 teaspoon sugar 1/2 cup or more chicken stock or water 2 tablespoons fish sauce.
Trees were separated into stem, branch and foliage components.
After removal of plants from the field, leaves were separated from stem.
In the case of the RG mutant, the leaf biomass would need to be removed and separated from stem material either during or post-harvest in order to optimize biorefining costs.
During embryonic shoot meristem formation, the two basic functions of the meristem need to be established in spatially separated domains: stem cell maintenance in the meristem center, and organ initiation in the periphery [ 3, 40].
The 100-d-old plant was separated into root, stem and leave.
A separate stem is used to attach the disks and the small blade to the 4 1/2-cup bowl.
