Scientists uncover key to enhancing cancer-killing T cells

T cells are the key immune system component involved in killing cancer. Tumors produce signals that turn off these T cells, partially by forcing them to progressively differentiate (mature) into a hypofunctional state known as exhaustion.

Scientists unravel iron-based memory mechanism in bacteria

Scientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms when millions of bacteria come together on a single surface.

New organoid model could lead to personalized treatments for colon-related diseases

A team at the Medical University of South Carolina and Cincinnati Children's has developed a sophisticated model for studying the diseased colon that could lead to the development of personalized treatments for colon-related diseases, such as cancer and inflammatory bowel disease (IBD).

Groundbreaking technology developed to extract mesenchymal stem cells from pure bone marrow

Researchers from the Critical Analytics for Manufacturing Personalized-Medicine (CAMP) Interdisciplinary Research Group (IRG) of Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, in collaboration with the Agency for Science, Technology and Research (A*STAR) Bioprocessing Technology Institute (BTI) and National University Health System (NUHS), have developed a groundbreaking technology capable of extracting mesenchymal stem cells (MSCs) directly from pure bone marrow – also known as bone marrow aspirate (BMA), a pivotal source of MSCs – without dilution.

Stem-cell-derived brain cells hold promise for Alzheimer's, Parkinson's research

Researchers at the University of Wisconsin–Madison have identified a protein key to the development of a type of brain cell believed to play a role in disorders like Alzheimer's and Parkinson's diseases and used the discovery to grow the neurons from stem cells for the first time.

Nerve-immune system cross-talk: Key to zebrafish heart regeneration

Unlike humans, zebrafish can completely regenerate their hearts after injury. They owe this ability to the interaction between their nervous and immune systems, as researchers led by Suphansa Sawamiphak from the Max Delbrück Center now report in the journal Developmental Cell.

Novel tool can help with analysis of single cell data

CITE-seq (cellular indexing of transcriptomes and epitopes) is an RNA sequencing-based method that simultaneously quantifies cell surface protein and transcriptomic data within a single cell readout.

Uncontrolled growth as a cancer cell's weakness

Growth is a fundamental biological process and a prerequisite for living organisms to develop and reproduce. The processes of cell growth (i.e. the production of new biomass) and of cell division must be coordinated with each other.

New insights into how cells maintain their identity over generations

Every cell in the human body contains the same genetic instructions, encoded in its DNA. However, out of about 30,000 genes, each cell expresses only those genes that it needs to become a nerve cell, immune cell, or any of the other hundreds of cell types in the body.
