Brain Organoids: Modeling Human Brain Development
What Are Brain Organoids and Why They Matter Brain organoids are tiny, lab-grown clusters of neural tissue that resemble certain aspects of the human brain. Each organoid starts from stem cells and, over several months, self-organizes into layered structures that mimic early brain development. Scientists use these miniature brains to study how neural circuits form,…

Two Parallel Blood Formation Systems Revealed by DKFZ Method
Introduction: A Paradigm Shift in Blood Formation For decades, scientists have viewed hematopoiesis, the process of blood formation, as a linear cascade: stem cells give rise to a lineage that eventually forms the diverse cells circulating in our blood. Recent research from the German Cancer Research Center (DKFZ) challenges this view by uncovering not one,…

Planarian stem cells reveal global signals drive regeneration
Planarian stem cells challenge the traditional view of stem cell niches In a breakthrough study published in Cell Reports, scientists from the Stowers Institute for Medical Research reveal that planarian stem cells do not rely on a fixed, nearby niche to regulate their fate. Instead, these cells respond to signals emanating from distant parts of…
