As these regulatory pathways are often impeded on in cancer stem cells, this knowledge could offer us the possibility to directly target misregulated pathways with specific drugs.
Predicting stem cell fate requires knowledge of how extracellular stimuli are integrated with intracellular signaling networks.
As cell choice is at the heart of stem cell biology, this knowledge base will guide future research into manipulating normal or disease-related cells for ultimate therapeutic benefit.
And so, while consistent with other studies showing improved spatial memory in the MWM following intrahippocampal stem cell delivery14,16,17, to our knowledge, our study is the first to show robust longer-term effects on cognition (greater than 6 weeks) after transplantation of clinically applicable human NSCs in immunosuppressed AD mice.
Beyond bench skills, Lindvall says that stem cell scientists need a knowledge of ethics.
Researchers have now observed similar patterns on many other issues – from gun control to fracking and stem cell research – where greater knowledge seems to increase political polarisation.
I conclude that in the current state of knowledge, stem cell research needs to continue and be allowed to unfold as the narrative of a story.
It is evident that a prerequisite for studying stem cell niches is detailed knowledge about the identity and precise localization of stem cells themselves.
However, to our knowledge, stem cell pools in p53 mutant mice are not universally elevated (Reviewed in Solozobova and Blattner, 2011).
Integrating our knowledge of gene expression patterns with the emerging knowledge regarding stem cell lineages and their interactions offers us an unprecedented opportunity to understand this phase of mammary development.
In the light of new knowledge, some stem cell biologists are making more guarded predictions about the imminence of stem cell therapy.
