Pooling all the cross-dated pre-fire
stems at a particular site gives a better approximation of maximum time - since - fire in the form of a bell - shaped or skewed - to - left distribution of the number of residual, cross-dated pre-fire stems going back in time from the actual date of fire (figure 5).
Bone marrow - derived mesenchymal
stem cells (BMDMSC) are of
particular interest in orthopedics, as cells in this lineage are involved in osteogenic differentiation of cells
at the
site of bone generation and regeneration.
