CB CD34+ cells were found in clusters at the vicinity of the central area formed by osteo-induced BMSC, as it has been described in vivo [1], [11], [30], suggesting that mixed spheroids formed a microenvironment that is representative of the subendosteal niche, identified as such by human hematopoietic progenitor and stem cells.
The primary niche identified by content vendors is providing evidence-based content.
We also note that while there are multiple feasible collaborative architectures, there is currently substantial overlap among the potential niche contributions identified by the international partners.
Typically, in experimental research a niche is identified either by evaluating the prior research (or lack of prior research) (ROE) or by evaluating the real world being investigated (TOE).
Insights into the complex stem cell niche have identified the cell material interface to be a potent regulator of stem cell fate via material properties such as chemistry, topography and stiffness.
However, although Thetela (1997: 105) claimed that when evaluating the real world (TOE) "both good or bad performances are equally interesting topics worth investigating", when a niche is identified in the real world (for example the fact that vocabulary is often ignored, as in example (5) below), the evaluation has to be negative in order to justify the research.
Recently, Bolnick et al. [6] reviewed support for the concept of the 'individual niche', and identified evidence from 97 species across a broad range of taxa.
Niche components identified in OS regions included cell adhesion molecules (CAMs), growth factors, cytokines, extracellular matrix and secreted proteins like neurotropins (table 3).
Using gel or saline instillation sonohysterography, a niche is identified in the scar in more than half of the women who had had a CS, most with the uterus closed in one single layer, without closure of the peritoneum.
At the intersection of these differentiation waves, adult bone marrow CD45− Nes-GFP+ cells (Mendez-Ferrer et al., 2010) converged with bone marrow HSC niche cells identified by the expression of stem cell factor (Ding et al., 2012).
For example, niche-innovations identified in the socio-technical study are implemented as scenario options in the model.
