Lab-created mini retinas allow researchers to understand retinal ganglion cell development

IUPUI biologists are growing 'mini retinas' in the lab from stem cells to mimic the growth of the human retina. The researchers hope to use the research to restore sight when critical connections between the eye and the brain are damaged.

Research uncovers how sleeping stem cells in the mammary gland are awakened at puberty

Walter and Eliza Hall Institute researchers have discovered how the growth of milk-producing mammary glands is triggered during puberty. Sleeping stem cells in the mammary gland are awoken by a protein dubbed FoxP1, according to the research that was published today in the journal Developmental Cell.

Skin cells show minimal damage, maximum pigmentation when exposed to sunlight every 48 hours

Skin cells show the least amount of DNA damage and produce the most amount of melanin when exposed to sunlight in 48 hour windows, according to new study.

Researchers track where tetracycline antibiotics go in human cells

We know that antibiotics treat bacterial infections. We also know why they work. Tetracycline antibiotics, for example, stop bacteria from making protein. Like a boot on a wheel, the drugs bind to the bacterial cell's ribosome--where protein is made--and prevent it from working. Without protein, the bacteria weaken and die.

'Cancer Gene Census' could help find drug targets and design treatments

Researchers at the Wellcome Sanger Institute have created the first comprehensive summary of all genes known to be involved in human cancer, the "Cancer Gene Census". Describing all genes strongly implicated in causing cancer, the Census also describes how they function across all forms of this disease.

Bioengineering scientists propose new paradigm for research into cardiovascular diseases

Thrombosis-on-a-chip, vasculature-on-a-chip and engineered models of human cardiac fibrosis are just a few of the new technologies revolutionizing research into human cardiovascular disease--a condition responsible for 17 million deaths per annum globally.

New approach using 'cellular dust' offers hope for regenerative medicine

While stem cells have the most therapeutic potential, the benefits of regenerative medicine may best be mobilized using extracellular vesicles (EVs), also known in the past as "cellular dust".

Study: Atg2 tethers pre-autophagosomal membrane to endoplasmic reticulum during autophagosome formation

Postdoctoral Researcher Tetsuya Kotani, Associate Professor Hitoshi Nakatogawa, Honorary Professor Yoshinori Ohsumi and colleagues at Tokyo Institute of Technology have analyzed the Atg protein Atg2, whose function had been completely unknown, and have discovered that Atg2 tethers the pre-autophagosomal membrane to the endoplasmic reticulum during autophagosome formation.

Map of human liver cells reveals molecular make-up of individual cells

A map of the cells in the human liver has been created by University Health Network Transplant Program and University of Toronto researchers, revealing for the first time differences between individual cells at the molecular level which can have a profound impact on their behaviour in tissue, tumours and disease.
