Scientists reveal communication system between knee joint and developing bones in mice

Scientists from the Memorial Sloan Kettering Cancer Center, US, have revealed a communication system between the knee joint and developing bones in mice, which controls bone growth during early development and after injury.

Princeton scientists test cell-culture system to aid study of HBV infections

Scientists from Princeton University's Department of Molecular Biology have successfully tested a cell-culture system that will allow researchers to perform laboratory-based studies of long-term hepatitis B virus (HBV) infections

Low vitamin D may affect recovery of injured corneas

Injury or disease in combination with too little vitamin D can be bad for the window to your eyes. The three-layer, transparent cornea at the front of the eyes focuses the light coming in. But its prominent position also puts it at risk for injury from an errant mascara wand or over-prodding finger or a car accident.

LMU neurobiologists present new theory for origin of grid cells

Ludwig-Maximilians-Universitaet in Munich neurobiologists present a new theory for the origin of the grid cells required for spatial orientation in the mammalian brain, which assigns a vital role to the timing of trains of signals they receive from neurons called place cells.

Researchers show how hematopoietic stem cells detect and react to infections

Researchers at the University of Zurich have shown for the first time that hematopoietic stem cells detect infectious agents themselves and begin to divide - that is, without signals from growth factors.

Lunatic fringe gene plays role in regulating fate of neural stem cells

The discovery that the brain can generate new cells - about 700 new neurons each day - has triggered investigations to uncover how this process is regulated.

Two cell types partner to protect pancreatic tumors from immune attack

Two cell types work together to protect pancreatic tumors from destruction by the immune system. But, blocking this partnership may restore the system's ability to attack these same tumor cells.

Scientists manage to permeate living cells with small antibodies

Scientists at the Technische Universität Darmstadt, Ludwig Maximilians University Munich and the Leibniz Institute for Molecular Pharmacology have managed to introduce tiny antibodies into living cells. The researchers now report on the synthesis and applications for these nanobodies in "Nature Chemistry".

Study shows how cells feel their way through the surroundings

Cells push out tiny feelers to probe their physical surroundings, but how much can these tiny sensors really discover? A new study led by Princeton University researchers and colleagues finds that the typical cell's environment is highly varied in the stiffness or flexibility of the surrounding tissue, and that to gain a meaningful amount of information about its surroundings, the cell must move around and change shape.

Developing software for cell and gene therapy supply chain tracking

The first thing is, to always remember that we're dealing with a living drug, cells, which are very sensitive to environmental conditions, such as temperature and humidity etc. All of those things can impact on the viability of the drug and its effectiveness.

UW-Madison researchers jump major hurdle on path toward wider use of stem cells

Since highly versatile human stem cells were discovered at the University of Wisconsin-Madison nearly 20 years ago, their path to the market and clinic has been slowed by a range of complications.

Researchers get closer to finding out how cells and their nucleus grow at constant ratio

Over a century since scientists first observed that cells and their nucleus grow at a constant ratio to each other, we are now closer to finding out how.

Scientists develop new method to accurately determine functional age of cells

Sure, you know how old you are, but what about your cells? Are they the same age? Are they older, younger? Why does it matter?

JAX researchers explore how dendritic cells promote adaptive immunity to virus

A research team led by Jackson Laboratory Professor Karolina Palucka, M.D., Ph.D., in collaboration with a research team at Institut Curie in France led by Dr. Nicolas Manel, have addressed a long-standing puzzle of immunology: How do dendritic cells (DCs) do their job of promoting adaptive immunity to a virus while avoiding getting infected themselves?
