Researchers Identify Proteins to Reprogram Fibroblasts into Limb Progenitor Cells

In a collaborative study, researchers from Kyushu University and Harvard Medical School have identified proteins that can turn or "reprogram" fibroblasts -; the most commonly found cells in skin and connective tissue -; into cells with similar properties to limb progenitor cells.

Microbial Sensor Unlocks Path to Personalized Blood Stem Cell Therapy

A microbial sensor that helps identify and fight bacterial infections also plays a key role in the development of blood stem cells, valuable new insight in the effort to create patient-derived blood stem cells that could eliminate the need for bone marrow transplants.

Mathematical Models and Biological Dynamics in Embryo Development

One of life’s enduring fundamental questions revolves around the process of development. Consider human growth—how do cells autonomously arrange themselves into structures like skin, muscles, or bones? How do they coalesce to form intricate organs such as the brain, fingers, or spine?

Towards A Better Understanding of Early Human Embryonic Development

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns.

How Scientists are Using iPSCs to Develop New Therapies

In 1998, scientists reported being able to derive cells from human embryos that could develop into almost any cell in the body. In 2007, the field took a huge leap when scientists discovered they could reprogram human adult skin cells to act like these embryonic stem cells.

New Method Creates Embryo-Like Structure That Mimics Gastrulation

Gastrulation, the process where an embryo reorganizes itself from a hollow sphere into a multilayered structure, is considered a "black box" of human development.

The Function of Stem Cell Barriers in the Treatment of Fertility

A set of molecules controls cells as they proliferate and take on certain identities and spatial placements within a human embryo as it develops.

New insights into early embryo development and origin of disease

The biochemical signals that determine the formation of the body pattern in the primate embryo have been found by scientists. This will direct research into human birth abnormalities and pregnancy loss.

Researchers discover new stem cell population that closely matches existing human stem cells

Reik lab researchers’ recent discovery describes a new subpopulation of human embryonic stem cells that closely match the cells present at the genomic “wake up call” of the 8-cell embryo stage in humans.

Experts identify the master regulator of Nodal signaling in human embryonic stem cells

A new study has led to the discovery that the Hippo signaling effector YAP1 is a master controller of Nodal signaling in hESCs for a process crucial to human development.
