RBC Membrane‐Camouflaged Nanosystem‐Mediated Synergistic Drug Combination for Enhanced Anti‐Tumor Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
An RBC membrane camouflaged, cell‐penetrating peptides R8‐based drug delivery system is constructed to achieve a synergistic combination of natural compounds triptolide (TP) and celastrol (Cel), inducing tumor cell apoptosis, reducing tumor metastasis invasion and triggering autophagy disorder in breast cancer and liver cancer.

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
