Antioxidants such as ascorbic acid can be used to expand MSCs while preserving their differentiation ability.
External radiation decreased the immunosuppressive effect of the glioma and provided the migratory capability for GCLRP-activated monocyte precursors of DCs to move into the tumoral hemisphere, preserving their differentiation into mature DCs within the tumoral hemisphere, which is associated with decreased tumor size and improved survival.
The published study has demonstrated that ES cells preserve their differentiation potential by maintaining a loosely bound fraction of histones and other chromatin-associated proteins, which through free exchange with bound histones and chromatin generate a state of active, "breathing" chromatin.
The cells were cultured on a reconstituted basement membrane to preserve their functional differentiation and estrogen responsiveness.
Moreover, cell polarity appeared well preserved on this substrate, so polarized cells like hepatoma HepaRG cells might maintain their differentiation status and act as primary human hepatocytes for hepatotoxicity testing.
This preserved their beautiful feathery branching shapes.
Thus, they preserved their traditions.
This demonstrates that on average, orthologs preserved their expression network.
However, a major problem remains in clinical practice, which is the question of whether stem cells preserve their self-renewal and differentiation potential in the culture conditions or not.
In the hematopoietic system, Gfi1 plays a key role in restricting HSC proliferation and preserving their functional integrity [13], [14], in controlling T cell differentiation [15], [16], and in determining the differentiation of neutrophils [17], [18] as well as dendritic cells [19].
