PP 3: Src Kinase Negative Control Guide
2026-09-14
1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine, sold as PP 3, is a research use only chemical used as a negative control for Src inhibitor PP 2. Its value is interpretive: matched PP 3 exposure helps distinguish Src-dependent effects from vehicle effects and unrelated cell signaling pathway modulation.

Cell Tumbling and Nuclear Mechanotransduction
2026-09-13
Ayushman and colleagues identify cell tumbling as a rapid three-dimensional movement in sliding hydrogels that enhances mesenchymal stem cell differentiation. Their experiments connect seconds-to-minutes-scale matrix deformation with nuclear chromatin remodeling, establishing a mechanobiological route by which fast cellular movements can influence long-term cell fate.
