Why Ergonomic Pipetting in a Laboratory is Important

If you spent an hour sat at a laminar flow cabinet pipetting stacks of cell culture plates that needed to be passaged or fed, then once all of the plates were back in the incubator, you probably stretched your back to loosen the muscles that had tensed while you were working.

DNA Damage Repair and the Progression of the Cell Cycle

All stages of the cell cycle in normal cells are tightly controlled. In cancer cells, several proteins and genes that impact the progression of the cell cycle are overexpressed or mutated and turn into oncogenes.

Human Cell Models of the Developing Cortex

Research into the mechanisms of early brain development, especially that of the cortex, is important in aiding our understanding of how the brain develops so that we can also understand how neurodevelopmental and neuropsychiatric disorders occur. Studying human brain development in vivo is incredibly difficult, as is studying the development of most mammalian organisms.

	Chemotherapy-induced senescent cells eat neighboring cells A US-based team of scientists has uncovered that chemotherapy can force cancer cells into a state of senescence. A new study has shown that this can propel cancer growth as these cells eat neighboring cells alive, allowing the senescent cells to endure. Researchers at the Tulane School of Medicine, New Orleans, LA, have recently published a paper revealing their findings from a study they conducted, which looked into the activity of senescent cells.

	Lab-grown, testosterone-producing cells could help treat hypogonadism esearchers at the University of Southern California (USC) have managed to grow human, testosterone-producing cells in the laboratory, a development that could lead to improved treatment of low testosterone levels (hypogonadism). The new approach could lead to a way of treating the condition with personalized treatment cells rather than hormonal therapy, which is associated with side effects, including an increased risk for other diseases.

	Confocal Reflection Microscopy for Cell Migration Studies Cell migration occurs throughout life as a response to internal and external signals, and can as such be indicative of changes occurring in the body. Imaging this movement and what processes control it can be critical in understanding cell behavior, development, and disease.
