Breakthrough for Tomorrow's Dentistry

New knowledge on the cellular makeup and growth of teeth can expedite developments in regenerative dentistry - a biological therapy for damaged teeth - as well as the treatment of tooth ...

Placenta Is Initiated First, as Cells of a Fertilized Egg Divide and Specialize

The first stages of placental development take place days before the embryo starts to form in human pregnancies. The finding highlights the ...

Uncovering the Clock That Sets the Speed of Embryo Development

Why do pregnancies last longer in some species than others? Researchers have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins are ...

Generation of Three-Dimensional Heart Organoids

New Insight Into Mammalian Stem Cell Evolution

The genes regulating pluripotent stem cells in mammals are surprisingly similar across 48 species, researchers report. The study also shows that differences among these 'gene regulating ...

Coaxing Single Stem Cells Into Specialized Cells

Researchers have developed a unique method for precisely controlling the deposition of hydrogel, which is made of water-soluble polymers commonly used to support cells in experiments or for ...

Researchers Pinpoint Hierarchy of Breast Cancer Cells as Potential Cause for Treatment Resistance

Researchers say it can take cells in different forms or 'life stages' to cause cancer to grow and ...

Move Over Akita: Introducing 'Kuma Mutant' Mice for Islet Transplantation Research

Scientists have used a gene editing technique to establish a novel mouse model of permanent neonatal diabetes -- the immune-deficient Kuma mutant mice with a specific deletion in the Insulin2 (Ins2) ...

Researchers Discover Stem Cells in Optic Nerve That Preserve Vision

Researchers have for the first time identified stem cells in the region of the optic nerve, which transmits signals from the eye to the brain. The finding presents a new theory on why the most common ...

How Airway Cells Work Together in Regeneration and Aging

Researchers have identified the process by which stem cells in the airways of the lungs switch between two distinct phases -- creating more of themselves and producing mature airway cells -- to ...

'Self-Eating' Process of Stem Cells May Be the Key to New Regenerative Therapies

The self-eating process in embryonic stem cells known as chaperone-mediated autophagy (CMA) and a related metabolite may serve as promising new therapeutic targets to repair or regenerate damaged ...

A Never-Before-Seen Cell State May Explain Cancer's Ability to Resist Drugs

Scientists have identified an unusual cell state that emerges early in tumor evolution and supports a cancer's ability to outwit ...

Brain Tumors May Be Seeded from Distant Site

A mouse model of glioblastoma, an aggressive type of cancer that can occur in the brain, suggests that this recalcitrant cancer originates from a pool of stem cells that can be a significant distance ...

Skin Stem Cells Shuffle Sugars as They Age

Researchers have shown by in vitro experimentation that changes of glycans in mouse epidermal stem cells may serve as a biomarker of aging. Further, by overexpression of specific glycogenes in mouse ...

The Hair-Raising Reason for Goosebumps

Researchers have discovered that the cells that cause goosebumps are also important for regulating the stem cells that regenerate hair. In the skin, the muscle that contracts to create goosebumps is ...

Researchers 3D Print a Working Heart Pump With Real Human Cells

In a groundbreaking new study, researchers have 3D printed a functioning centimeter-scale human heart pump in the lab. The discovery could have major implications for studying heart disease, the ...

New Clues from Fruit Flies About the Critical Role of Sex Hormones in Stem Cell Control

In one of the first studies addressing the role of sex hormones' impact on stem cells in the gut, scientists outline new insights showing how a steroidal sex hormone, ecdysone, drastically ...

RNA Key in Helping Stem Cells Know What to Become

If every cell has the same genetic blueprint, why does an eye cell look and act so differently than a brain cell or skin cell? In a new study, researchers come one step closer to solving this ...

Order from Noise: How Randomness and Collective Dynamics Define a Stem Cell

Without stem cells, human life would not exist. Due to them, a lump of cells becomes an organ, and a fertilized egg develops into a baby. But what actually makes a stem cell? Are these a stable ...

Epigenetics: What the Embryo Can Teach Us About Cell Reprogramming

Cell reprogramming provides an outstanding opportunity for the artificial generation of stem cells for regenerative medicine approaches in the clinic. As current cell reprogramming methods are low in ...

Getting a Grasp on India's Malaria Burden

A new approach could illuminate a critical stage in the life cycle of one of the most common malaria ...

A Simpler Way to Make Sensory Hearing Cells

Scientists are whispering the secrets of a simpler way to generate the sensory cells of the inner ear. Their approach uses direct reprogramming to produce sensory cells known as 'hair ...

COVID-19: Study Shows Virus Can Infect Heart Cells in Lab Dish

A new study shows that SARS-CoV-2, the virus that causes COVID-19 (coronavirus), can infect heart cells in a lab dish, indicating it may be possible for heart cells in COVID-19 patients to be ...

Nanoparticle for Overcoming Leukemia Treatment Resistance

One of the largest problems with cancer treatment is the development of resistance to anticancer therapies. A research team found that repurposing a commonly used chemotherapy drug using a ...
