Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Sustainable Fabrication of Tailored Bone Substitutes: From High‐Throughput Scaffold Manufacturing, Scaled‐Up HMSC Expansion to Dynamic Cultivation in a Perfusion Bioreactor

Advanced Science, EarlyView.
ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...

Wet synthesis of carbonated hydroxyapatite

Proceedings of the National Academy of Sciences of Belarus, Chemical Series, 2019
Carbonated hydroxyapatite of predominant B-type of substitution has been synthesized at various temperatures, carbonate concentrations and time of immersion in mother solution. Carbonated hydroxyapatite synthesized at 80 °C contains the largest amount (up to 9 wt.%) of calcite impurity and has a low specific surface area (40 m2/g).

Ubiquitination of ACSL4 by Parkin Suppresses Ferroptosis and Rescues Glucocorticoid‐Induced Bone Loss

Advanced Science, EarlyView.
GCs reduce Parkin, leading to ACSL4 accumulation and PUFA‐phospholipid‐driven ferroptosis in BMSCs, which impairs osteogenesis and promotes adipogenesis, causing GIOP. Parkin restoration (via OE‐Parkin or Parkin‐LNP@DSS6) ubiquitinates and degrades ACSL4, inhibiting ferroptosis, rescuing bone formation, and rescues GIOP bone loss.

A Programmable Calcification Nanoplatform for Loco‐Regional Calcification‐Immune Hepatocellular Carcinoma Therapy

Advanced Science, EarlyView.
An in situ‐grown BP‐CaO2 nanoplatform supplies coordinated Ca2+, endogenous phosphate, and oxidative stress to convert tumor calcification from a passive endpoint into an active immune‐remodeling process. Widespread hydroxyapatite deposition is visualized by CT, while multi‐omics reveals MCOLN2 as a calcium‐responsive mediator linking biomineralization

Coupled effect of particle size of the source materials and calcination temperature on the direct synthesis of hydroxyapatite

Royal Society Open Science, 2021
We report the effect of controlled particle size (obtained by using 80, 100, 120, 140 and 200 mesh) of the source materials on the synthesis of a well-known biomaterial, hydroxyapatite (Hap).

In Situ Profiling of Nanoscale Strains Uncovers Mechano‐Architectural Predictors of Aging and Osteoarthritis Emergence

Advanced Science, EarlyView.
In situ mechanical loading of osteoarthritis‐prone murine knee joints reveals that spatial alterations in subchondral plate microarchitecture precede cartilage loss and promote a shift from coordinated epiphyseal strain dissipation in healthy joints to focal subchondral strain concentration in osteoarthritis‐prone joints.
