Landmark Study Signals Shift in Thinking About Stem Cell Differentiation

StemBook: Landmark Study Signals Shift in Thinking About Stem Cell Differentiation (stem cells)

Tallahassee, FL, USA – A pioneering new study led by Florida State University (FSU) biologists could fundamentally change our understanding of how embryonic stem cells differentiate into specific cell types. The research, published today in the journal Stem Cell Reports, calls into question decades of scientific consensus about the behavior of embryonic stem cells as they transition to endoderm, a class of cell in animal embryos that gives rise to the digestive and respiratory systems.

Dormant Neural Stem Cells in Fruit Flies Activate to Generate New Brain Cells

StemBook: Dormant Neural Stem Cells in Fruit Flies Activate to Generate New Brain Cells (stem cells)

Singapore, Singapore – How dormant neural stem cells in fruit flies are activated and generate new neurons is described in a new research study by Duke-NUS Medical School. The findings could potentially help people with brain injury or neuronal loss, if similar mechanisms apply in humans. Publishing in PLOS Biology, the research team, led by Associate Professor Wang Hongyan, Deputy Director of Duke-NUS’ Neuroscience and Behavioural Disorders Programme and lead author of the study, described the process and molecules involved in reactivating fruit flies’ (also known by their scientific name, Drosophila) dormant neural stem cells, which can activate and generate new neurons.

Introduced a New Paradigm of Cell Transplantation with Scaffold Microrobots

StemBook: Introduced a New Paradigm of Cell Transplantation with Scaffold Microrobots (stem cells)

Daegu, Korea – A research team from Daegu Gyeongbuk Institute of Science and Technology (DGIST) succeeded in developing stem cell delivery of scaffold microrobot that can precisely deliver cells to a target body tissue. This research achievement is expected to enhance the treatment safety and efficiency of degenerative neural disorders as it can precisely transplant the exact amount of stem cell-based treatment cells to human body tissues and organs.

StemBook:  First Blood-Brain Barrier Chip Using Stem Cells Developed by Ben-Gurion University Researchers

Beer-Sheva, Israel – Researchers at Ben-Gurion University of the Negev (BGU) and Cedars-Sinai Medical Center in Los Angeles have, for the first time, duplicated a patient's blood-brain barrier (BBB), creating a human BBB chip with stem cells, which can be used to develop personalized medicine and new techniques to research brain disorders.

Study Reveals Factors Behind Embryonic Stem Cell State

ACS news

Washington, DC, USA – What if doctors had a remote control that they could use to steer a patient’s own cells to a wound to speed up the healing process? Although such a device is still far from reality, researchers reporting in the ACS journal Nano Letters have taken an important first step: They used near-infrared light and an injected DNA nanodevice to guide stem cells to an injury, which helped muscle tissue regrow in mice.

Surprising Research Result: All Immature Cells Can Develop into Stem Cells

Copenhagen, Denmark – New sensational study conducted at the University of Copenhagen disproves traditional knowledge of stem cell development. The study reveals that the destiny of intestinal cells is not predetermined, but instead determined by the cells' surroundings. The new knowledge may make it easier to manipulate stem cells for stem cell therapy. The results have just been published in Nature.

Scientists Grow Precursors For Human Pigment Cells

kobe news

Kobe, Japan – Our hair, skin and eyes are colored by a pigment called melanin, which is produced by pigment cells called melanocytes. Scientists have used stem cell technology to successfully create melanocyte precursor cells. These cells can be used in research on melanoma and other pigment cell-related illnesses. The findings were published on March 6 in the online edition of Pigment Cell & Melanoma Research.

Tissue Engineering Applications Combining Biomaterial Scaffolds with Stem Cells Will Facilitate Delivery of Targeted Therapies

STJ PR
Noted stem cell researchers present a state-of-the-art review in the inaugural article published in StemJournal

Amsterdam, NL – StemJournal, a new open access, peer-reviewed journal published by IOS Press, announces publication of its inaugural article, "Combining Stem Cells and Biomaterial Scaffolds for Constructing Tissues and Cell Delivery" by Stephanie M. Willerth, PhD, and Shelly E. Sakiyama-Elbert, PhD. This timely overview of the available biomaterials for directing stem cell differentiation as a means of producing replacements for diseased or damaged tissues is a comprehensive update of the classic review published in StemBook in 2008.
