Loss of tumor suppressor p53 reshapes Wnt signaling to drive mutant cell expansion

A protein known as p53 is, of all tumor suppressors in human cancer, the most frequently altered by gene mutations.

Scientists discover new cell type that may help regulate blood vessel growth in the heart

Researchers have discovered a new cell type that may help regulate blood vessel growth in the heart during development and in response to injury, according to a study from Weill Cornell Medicine.

Slow-growing progenitor cells cause smooth brains in common marmosets

Most primate species have a relatively large brain with a surface marked by pronounced bulges and furrows. This is not the case with common marmosets (Callithrix jacchus). The brains of these small monkeys are smooth and virtually unfolded.

Brain organoids reveal new clues for childhood epilepsy treatments

Tiny, year-old human brain organoids that mimic the brain of a newborn are providing new clues to potential treatments for a leading genetic cause of childhood epilepsy that typically manifests as the brain matures shortly after birth.

Genetic system converts scar-forming cells into neurons to restore movement after spinal cord injury

What if cells that form scars after a spinal cord injury could become part of the repair process? Researchers have developed a genetic system that converts certain scar-forming cells into neurons, improving movement in mice and rats with spinal cord injuries.

Intracortical microstimulation: Evoking artificial perception and engaging plasticity-based modulation

But creating a long-lasting electronic connection with the brain is complicated. Conventional microwire and silicon electrodes are much stiffer than soft brain tissue.

New discovery overturns a prevailing model of brain development

For centuries, scientists have thought of the brain as a single, unified organ. But new research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years.

Two collagen receptors cooperate to enhance cranial bone regeneration

Bone repair depends on skeletal progenitor cells (SPCs) moving to injured areas and developing into bone-forming cells, but how these cells respond to their surroundings remains unclear.

Crucial brain stem cells rely on metabolic pathways to make decisions

As the human brain takes shape before birth, a remarkable type of stem cell helps give it many of the features that make it distinctly human.

Researchers uncover molecular pathway driving craniosynostosis

Craniosynostosis is a congenital developmental disorder in which the skull's cranial sutures fuse prematurely.

AI identifies key gene driving aging in blood stem cells

Stem cells possess the unique ability to self-renew and transform into different types of cells. For example, rare hematopoietic stem cells found in bone marrow can become any type of blood cell.

Penn State team lays groundwork to 3D print spheroids for regenerating bone tissue

An interdisciplinary team of engineers and chemists at Penn State has laid the groundwork to 3D print spheroids - tiny clusters of living cells - capable of regenerating bone tissue in response to severe trauma or infections.

$Muscle cells play a vital role in repairing fractured bones$

Muscle cells play a vital role in repairing fractured bones

Bone healing is a complex process that depends on the coordinated activity of many different cell types.

Cannabis compounds may weaken glioblastoma response to chemotherapy and radiation

Several cannabinoids reduced chemotherapy- and radiation-induced apoptosis in glioblastoma cell models, with effects linked to reduced apoptotic priming, increased pro-survival signaling, and G1 cell-cycle arrest. The findings raise concern that cannabinoid exposure could interfere with some cancer treatments, although the results are limited to laboratory models and require in vivo and clinical validation.

New study reveals genetic drivers of inherited bone marrow failure syndrome

Inherited bone marrow failure syndrome, or IBMFS, describes a group of disorders in which inherited genetic abnormalities impair the bone marrow's ability to produce sufficient healthy blood cells.

Tuft cell-like cancers exhibit unique biological characteristics across multiple organs

A growing body of evidence suggests that a rare epithelial cell type known as the tuft cell may play a far more significant role in cancer than previously recognized.

Versatile receptor protein plays critical role in regulating tissue repair

A comprehensive new review highlights the expanding importance of Lgr6, a member of the G protein-coupled receptor family, as a critical regulator of tissue homeostasis, injury repair, and disease development across multiple organ systems.

Cell village approach reveals genetic differences in cell fitness

How readily a cell divides and how well it survives is fundamental to life, shaping everything from organ size to the body's ability to withstand disease.

Cell junction proteins regulate stem cell signaling and tissue homeostasis

In many animal tissues, stem cells continually divide to create new cells that replace old or damaged ones. However, this capacity requires strict regulation, as uncontrolled stem cell proliferation can disrupt tissue homeostasis and contribute to tumorigenesis.

Iowa State study identifies potential new target for leukemia treatment

In leukemia's most aggressive forms, the blood cell factories in our bone marrow falter. Instead of dividing and multiplying at their usual prolific pace, generating hundreds of billions of new cells daily, some precursor cells stall out at an immature stage.
