Moduli space actions on the Hochschild Co-Chains of a Frobenius algebra I: Cell Operads
, 2006 This is the first of two papers in which we prove that a cell model of the moduli space of curves with marked points and tangent vectors at the marked points acts on the Hochschild co--chains of a Frobenius algebra. We also prove that a there is dg--PROP

Controlled Cytoplast Arrest and Morula Aggregation Enhance Development, Cryoresilience, and In Vivo Survival of Cloned Sheep Embryos [PDF]
, 2021 Zona-free somatic cell transfer (SCT) and embryo aggregation increase throughput and efficiency of cloned embryo and offspring production, respectively, but both approaches have not been widely adopted.

Cell calcium, cell injury and cell death. [PDF]
Environmental Health Perspectives, 1984 The role of calcium in cell injury has been the subject of much recent investigation. The movement and redistribution of this cation from extra to intracellular compartments and the calcium shifts between intracellular compartments may well play a determinate role in the cell's reaction to injury.

Dynamics of cell-type transition mediated by epigenetic modifications [PDF]
arXiv, 2023 Maintaining tissue homeostasis requires appropriate regulation of stem cell differentiation. The Waddington landscape posits that gene circuits in a cell form a potential landscape of different cell types, wherein cells follow attractors of the probability landscape to develop into distinct cell types.

Tip cell overtaking occurs as a side effect of sprouting in computational models of angiogenesis [PDF]
BMC Systems Biology 2015, 9:86, 2015 During angiogenesis, endothelial cells compete for the tip position during angiogenesis: a phenomenon named tip cell overtaking. It is still unclear to what extent tip cell overtaking is a side effect of sprouting or to what extent a biological function.

Jamming and force distribution in growing epithelial tissue [PDF]
Phys. Rev. Research 3, 023129 (2021), 2020 We investigate morphologies of proliferating cellular tissues using a newly developed numerical simulation model for mechanical cell division and migration in 2D. The model is applied to a bimodal mixture consisting of stiff cells with a low growth potential and soft cells with a high growth potential; cancer cells are typically considered to be softer

Understanding the Warburg Effect: The Metabolic Requirements of Cell Proliferation
Science, 2009 Fuel Economy for Growing Cells Sophisticated 21st-century analyses of the signaling pathways that control cell growth have led researchers back to the seminal work of Otto Warburg, who discovered in the 1920s that tumor cells generate their energy in an ...

TGFβ1-induced cell motility but not cell proliferation is mediated through Cten in colorectal cancer [PDF]
, 2018 Cten (C-terminal tensin-like) is a member of the tensin protein family found in complex with integrins at focal adhesions. It promotes epithelial‐mesenchymal transition (EMT) and cell motility. The precise mechanisms regulating Cten are unknown, although
