12 °C vs. 18 °C, and 18 °C vs. 22 °C). Since the temperature shift from 8 °C to 12 °C did not decrease the cell number per polyp significantly (Fig.1b, c), we
Importantly, loss of E-cadherin disrupts not only cell–cell adhesion but also the orientation of cell divisions, including the planar orientation of cell divisions in simple epithelia25–29. However, the precise role of E-cadherin in division orientation is not known, and it remains unclear ...

The growth of certain insect structures involves orientated cell divisions and is one of the very few cases where growth seems to determine form 4 . Form seems to be determined by the spatial relationship between the cells which may be largely determined by cell movement and cell contact 3 . ...
cell stage when compaction occurs [1]. Further, cell divisions, activation, and inhibition of regulators like transcription factors lead to unique tissue patterns and organ shapes, which support multiple unique organ functions. Cell-cell communication is crucial for maintaining the spatial organization ...
Another study found that the results varied with different cut-off values of DN-ICSI time. When the cut-off value was 2 h, the implantation rate was strikingly higher in the < 2-h group than in the > 2-h group, but there was no significant difference between the two groups ...
The model is based on a Master equation which describes the time evolution of the probability that there arexprotein molecules present in a single cell at timetbetween cell divisions. This probability is given by the probability density functionp(x,t). We assume that the protein copy number ra...
In normal somatic cells, progressive telomere shortening along with cell divisions results in replicative senescence. Conversely, cancer cells aberrantly express the TElomerase Reverse Transcriptase (TERT) enzyme that forms a ribonucleoprotein (RNP) with Telomerase RNA (TR) and uses it as a template to...
