The study reveals that introducing progerin, a protein associated with accelerated aging, into cellular models of Alzheimer's Disease (AD) can hasten the development of AD-related traits. This innovative approach offers a more efficient method for studying AD mechanisms, potentially accelerating the discovery of new treatments.
Researchers utilize 3D printing to craft cerebral cortex tissues with organized neurons, offering potential treatments for brain injuries. This novel technique prints neural progenitors in layer-by-layer sequences, aiming for accurate tissue restoration in damaged brains.
The periosteum is a thin layer of connective tissue covering bone. It is an essential component for bone development and fracture healing. There has been considerable research exploring the application of the periosteum in bone regeneration since the 19th century. An increasing number of studies are focusing on periosteal progenitor cells found within the periosteum and the use of hydrogels as scaffold materials for periosteum engineering and guided bone development. Here, we provide an overview of the research investigating the use of the periosteum for bone repair, with consideration given to the anatomy and function of the periosteum, the importance of the cambium layer, the culture of periosteal progenitor cells, periosteum-induced ossification, periosteal perfusion, periosteum engineering, scaffold vascularization, and hydrogel-based synthetic periostea.
