Researchers develop a cell culture test to detect substances that harm the placenta and embryo

Researchers at ETH Zurich have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the augmented version is designed to help reduce the number of animal experiments.

Induced pluripotent stem cells hold great promise for regenerative medicine

The 2012 Nobel prize-winning discovery that ordinary cells could be coaxed to revert to their earliest pluripotent stage ushered in the era of ethical stem cell research.

Stem cell therapy can repair brain damage and improve memory function in mice

A one-time injection of an experimental stem cell therapy can repair brain damage and improve memory function in mice with conditions that replicate human strokes and dementia, a new UCLA study finds.

New RNA-sequencing method can help detect numerous modified small RNAs

A team led by a biomedical scientist at the University of California, Riverside, has developed a new RNA-sequencing method-- "Panoramic RNA Display by Overcoming RNA Modification Aborted Sequencing," or PANDORA-seq -- that can help discover numerous modified small RNAs that were previously undetectable.

Maturation of 'mini brain' organoids matches human brain development

A new study from UCLA and Stanford University researchers finds that three-dimensional human stem cell-derived 'mini brain' organoids can mature in a manner that is strikingly similar to human brain development.

New drug screening platform identifies inhibitors of SARS-CoV-2

Researchers in the UK and the United States have developed a stem-cell-based screening platform for identifying compounds that inhibit infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the causative agent for coronavirus disease 2019 (COVID-19).

Intermediate embryonic stem cell type could lead to advances in regenerative medicine

A team led by UT Southwestern has derived a new "intermediate" embryonic stem cell type from multiple species that can contribute to chimeras and create precursors to sperm and eggs in a culture dish.

Study provides new insight into the formation of neural crest cells

Last year, researchers at the University of California, Riverside, identified the early origins of neural crest cells -- embryonic cells in vertebrates that travel throughout the body and generate many cell types -- in chick embryos.

Novel discovery could lead to stem cell-based treatment for heart failure

Blocking an enzyme linked with inflammation makes it possible for stem cells to repair damaged heart tissue, new research from UC Davis Health scientists shows.

Researchers investigate why irregular heartbeats occur after stem cell transplantation

Stem cells are heavily studied around the world with the hope to revive damaged body parts unable to regenerate itself. Injured heart muscles are one of these areas which remain impaired in adults who have experienced heart attacks.

The 2019 3Rs prize awarded to two pieces of novel research

The 2019 3Rs prize has been jointly awarded to Dr Francesca Nunn and Dr Marta Shahbazi for papers describing research that reduces the number of chickens and mice respectively. The 3Rs prize is awarded by the NC3Rs and sponsored by GSK.

Scientists uncover why developing nerve cells take a wrong turn

A group of scientists from CECAD, the Cluster of Excellence 'Cellular Stress Responses in Aging-Associated Diseases,' have found a mechanism by which neurodevelopmental diseases concerning neurons can be explained: The loss of a certain enzyme, UBE2K, impeded the differentiation of stem cells by silencing the expression of genes important for neuronal differentiation and, therefore, the development and generation of neurons.

Study resolves contradictions surrounding p53 gene's role in pluripotent stem cell differentiation

The gene p53 is extremely important in cell biology and, hence, the world of cell replacement therapy. Its role is to regulate the cell cycle and halt the formation of tumors, leading to its nickname the "tumor suppressor gene."

Study explores how some mammals postpone development of their embryos

How do some mammals postpone the development of their embryos to await better conditions for having offspring? A recent study at the UW Medicine Institute for Stem Cell and Regenerative Medicine explored this reproductive enigma, which can occur in more than 130 species of mammals as well as in some marsupials.

Growing eggs and sperm to treat infertility

Scientists at the University of California, Los Angeles, have reported, in the journal Cell Reports, the mechanism of how the very early precursor or stem cells which eventually give rise to the germ cells, eggs and sperm, are formed over the course of development. This could help create eggs and sperms under laboratory conditions to help infertile people who don’t have sperms, or eggs, for instance.

Researchers use new technique to improve the ability to model lung diseases

Using a combination of pluripotent stem cells (cells that can potentially produce any cell or tissue type) and machine learning (artificial intelligence that allows computers to learn automatically), researchers have improved how they generate lung cells.

Moffitt researchers develop efficient method for creating mouse models to study melanoma

Genetically engineered mouse models are often used by scientists to study how the addition, deletion or mutation of genes affects the development of disease and effects of drugs.

New project could mark a pivotal advancement in therapies to address male sterility

Researchers from the University of Georgia, Emory University School of Medicine and the University of Pittsburgh have received a $2.9 million grant from the National Institutes of Health to test a novel method of producing viable sperm cells from skin cells.

Researchers uncover earlier origin of the neural crest in chick embryos

Neural crest cells -- embryonic cells in vertebrates that travel throughout the body and generate many cell types -- have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest stages of embryonic development.

Temporal fluctuations in protein concentrations can determine fate of stem cells

How do temporal variations in protein concentrations affect biology? It's a question that biologists have only recently begun to address, and the findings are increasingly showing that random temporal changes in the amount of certain proteins play a direct and significant role on biological processes.
