Stem cell-derived organoids mimic human parathyroid tissue

Patient-derived parathyroid organoids (PTOs) could pave the way for future physiology studies and drug-screening applications, as shown in a study published on October 27 in the journal Stem Cell Reports.

Making lab-grown brain organoids 'brainier'

By using stem cells to grow miniature brain-like organs in the lab, scientists have opened a new avenue for studies of neurological development, disease and therapies that can't be conducted in living people. But not all ...

Sterile mice produce rat sperm

Researchers generated rat sperm cells inside sterile mice using a technique called blastocyst complementation. The advance appears August 4 in the journal Stem Cell Reports.

Researchers devise sex-cell precursors with staying power

Human primordial germ cells (PGCs) are the early precursors of the eggs (oocytes) and sperm that are necessary to keep humankind alive and reproducing. Medical researchers attempt to study their function and development using ...

Teaching a computer program to track cells

Following the minuscule movements of every cell in a petri dish would be a painstaking task for any human. But teach a set of computer programs to do the job, and they can complete it quickly and even observe things that ...

Recreating the earliest stages of life

In their effort to understand the very earliest stages of life and how they can go wrong, scientists are confronted with ethical issues surrounding the use of human embryos. The use of animal embryos is also subject to restrictions ...
