we identify a programme of forces and changes to the cytoplasmic mechanical properties required for mouse embryo development from fertilization to the first cell division. Injected, fully internalized nanodevices responded to sperm decondensation and recondensation, and subsequent device behaviour suggested ...
(two projections were used here) and it is commonly used in single-cell RNA sequencing studies. Two mII oocytes were excluded as outliers, and one 2PN one-cell embryo failed to amplify and had to be abandoned (Table S3). The remaining 24 samples (n=12 each oocytes and one-cell embryos...

This is not some hallucinogenic trip. Rather,Steinertwas exploring a microscopic snail embryo in 3-D at the YURT, a virtual reality theater at Brown University. For her undergraduate senior thesis here, she dove into the past and future of scientific imaging. She was drawn to how beautiful an...
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. To achieve such reprogramming of neuronal identity, the researchers used a transcription factor called Fezf2, which long has been known for playing a central role in the development of corticospinal neurons in the embryo. ...

The p53 tumor suppressor protein is a DNA sequence-specific transcriptional regulator that, in response to various forms of cellular stress, controls the expression of numerous genes involved in cellular outcomes including among others, cell cycle arrest and cell death. Two key features of the p53 ...
