Cyclic AMP (cAMP) is the primary signaling molecule that drives aggregation and subsequent development. Pulses of cAMP are secreted by aggregating mounds of cells at 6-10 min intervals. Cells are chemotactic for cAMP (and for Ca2+). CAR1 cell surface receptor for cAMP has 7 transmembrane domains, homologous to rhodopsin.

Stem Cell Reports

In floating culture conditions, ESC aggregation to form EBs accompanied by LIF withdrawal leads EBs to mimic the early steps of in vivo cell differentiation (Desbaillets et al., 2000; Doetschman et al., 1985). By day 3–4, the outer cell layer of WT EB forms the PE, characterized by expression of endoderm markers such as GATA4 and by

How Cancer Spreads By Aggregating Platelets -- ScienceDaily

Aug 31, 2007 · How Cancer Spreads By Aggregating Platelets. The researchers also found that podoplanin present within lymphatic vessels -- which carry plasma and white blood cells -- also induces platelet aggregation, showing that a better understanding of how podoplanin and CLEC-2 bind together may provide information on how lymphatic vessels form and work.

Cell aggregation is frequently impaired during the growth of primary tumors and the formation of metastatic lesions. Cell aggregation depends on cell–cell adhesion; however, no rigorous approach exists to monitor and quantify it accurately in the absence of the confounding factors of cell–substrate adhesion and the resulting cell motility on the substrate.

Nov 21, 2018 · In this work, Pu et al. introduced a concept of "dormancy depth" that provides a unifying framework for understanding both persisters and viable but non-culturable cells. Subsequent mechanistic investigations revealed how ATP-dependent dynamic protein aggregation regulates cellular dormancy and resuscitation, the fine control of which facilitates bacterial drug tolerance.

Reduce CHO Cell Aggregation - Picturepark

Reduce CHO Cell Aggregation Chinese Hamster Ovary (CHO) cells are widely used in large-scale culture. These cells have conventionally been grown as attached cultures, but they will also grow in suspension, a property which has allowed for relatively simple scale up in stirred tank and airlift bioreactors.
