Biomimetic Scaffolds Enhance iPSC Astrocyte Progenitor Angiogenic, Immunomodulatory, and Neurotrophic Capacity in a Stiffness and Matrix‐Dependent Manner for Spinal Cord Repair Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
Through tuning biomimetic scaffold stiffness and matrix composition the reparative capacity of astrocyte progenitors is enhanced. Soft, collagen‐IV/fibronectin‐functionalized scaffolds promote progenitor growth while improving angiogenic, immunomodulatory, and neurotrophic capacity in a stiffness and matrix‐dependent manner, demonstrating the impact of

Influence of Hypoxia on a Biomaterial Model of the Bone Marrow Perivascular Niche

open access: yesAdvanced Healthcare Materials, EarlyView.
Hypoxia is a key factor in bone marrow physiology and hematopoietic stem cell behavior. Lower oxygen tension influences the secretion of vasculature‐derived hematopoietic regulatory factors and alters hematopoietic cell behavior in a conditioned medium hydrogel model of bone marrow. Cyclosporin A is used to mitigate normoxic stress during hematopoietic

Branching processes. II

Journal of Soviet Mathematics, 1987
The main results obtained from 1968 to 1983 in the theory of Markov branching processes and processes with transformations depending on the age of particles are reflected in this article. Along with the traditional sections (integral and local theorems, stationary measures), the survey includes sections devoted to statistics of branching processes. The
