Stem Cells News and Research

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Cancer driving protein plays crucial role in the development of lung cancer, study reveals

Lung cancer is the second leading cancer in the United States and the No. 1 cause of cancer-associated deaths.

Experts identify the master regulator of Nodal signaling in human embryonic stem cells

A new study has led to the discovery that the Hippo signaling effector YAP1 is a master controller of Nodal signaling in hESCs for a process crucial to human development.

Cell culture environments are unstable and drive reproducibility crisis

Culture environments of different cell types growing in culture vessels or Petri dishes vary significantly from each other and from conditions in the living body, potentially driving the "reproducibility crisis" in biomedical research, according to a team of KAUST bioscientists.

In vivo tracking of unlabeled stem cells using sugars

A Johns Hopkins Medicine scientist who spent 30 years figuring out how to put chemical labels into cells to track their movement in living tissues has found that certain self-renewing stem cells have built-in tracers -; made out of sugars -; that can do the job without added chemical "labels" when injected into mouse brains.

TAB1 gene plays a key role in maintaining stem cells during ovule formation in rice plants

Rice has long been a staple food for more than half the global population. The United Nations even declared 2004 the International Year of Rice to raise awareness and encourage action to protect and advance the crop for a rapidly growing population.

Different autism risk genes have similar effects on brain development, study finds

Autism spectrum disorder has been associated with hundreds of different genes, but how these distinct genetic mutations converge on a similar pathology in patients has remained a mystery.

New 'disease-in-a-dish' system developed to study oculocutaneous albinism

Researchers at the National Eye Institute have developed the first patient-derived stem cell model for studying eye conditions related to oculocutaneous albinism (OCA).

Neurons derived from human stem cells can predict the cardinal features of psychiatric illness

In a breakthrough that holds significant promise for early diagnosis and better treatment of psychiatric illness, researchers have for the first time used neurons derived from human stem cells to predict the cardinal features of a psychiatric illness, such as psychosis and cognitive deficits in patients with schizophrenia.

NRL scientists apply new methods to analyze cell behavior

Naval Research Laboratory researchers in the Chemistry Division apply their knowledge of biology in conjunction with materials to improve understanding of how cells and tissues organize and apply new methods to affect cell communication.

Research highlights opportunities to expand the manufacture of stem cells in space

The secret to producing large batches of stem cells more efficiently may lie in the near-zero gravity conditions of space. Scientists at Cedars-Sinai have found that microgravity has the potential to contribute to life-saving advances on Earth by facilitating the rapid mass production of stem cells.

Scientists discover how sponginess of stem cell nuclei controls cell differentiation

Researchers from Tokyo Metropolitan University have discovered how the sponginess and stickiness of stem cell nuclei controls how they "differentiate" into specialized cells. They found that the nucleus starts solid-like but becomes more fluid-like over time.

Severe lung injuries can trigger stem cells to undergo abnormal differentiation, study finds

Severe injuries to the lung from diseases such as COVID-19 trigger abnormal stem cell repair that alters the architecture of the lung. The aberrant stem cell differentiation in response to injury can prevent the restoration of normal lung function.

Researchers grow intestinal organoids to study why bats infected with viruses do not succumb to diseases

Experiments attempting to explain why bats can be infected with many viruses at a time without succumbing to diseases such as COVID-19-;knowledge that could help us to reduce the threat to humans of infectious disease-;have struggled until now with the fact that live wild bats make poor research subjects.
