As populations age across the world, osteoporosis and osteoporosis-related fractures are becoming the most prevalent degenerative bone diseases. More than 75 million patients suffer from osteoporosis in the USA, the EU and Japan. Furthermore, it is anticipated that the number of patients affected by osteoporosis will increase by a third by 2050. Although conventional therapies including bisphosphonates, calcitonin and oestrogen-like drugs can be used to treat degenerative diseases of the bone, they are often associated with serious side effects including the development of oesophageal cancer, ocular inflammation, severe musculoskeletal pain and osteonecrosis of the jaw.The use of autologous mesenchymal stromal cells/mesenchymal stem cells (MSCs) is a possible alternative therapeutic approach to tackle osteoporosis while overcoming the limitations of traditional treatment options. However, osteoporosis can cause a decrease in the numbers of MSCs, induce their senescence and lower their osteogenic differentiation potential.Three-dimensional (3D) cell culture is an emerging technology that allows a more physiological expansion and differentiation of stem cells compared to cultivation on conventional flat systems.This review will discuss current understanding of the effects of different 3D cell culture systems on proliferation, viability and osteogenic differentiation, as well as on the immunomodulatory and anti-inflammatory potential of MSCs.

The three-dimensional (3D) culture system has emerged as an indispensable platform for modulating stem cell function in biomedicine, drug screening, and cell therapy. Despite a few studies confirming the functionality of 3D culture, the molecular factors underlying this process remain obscure. Here, we have utilized a hanging drop method to generate 3D spheroid-derived mesenchymal stem cells (3D MSCs) and compared them to conventionally 2D-cultured MSCs.

Background: Current neurovascular unit isolation requires processing brain microvascular endothelial cells (BMECs) and neurons from separate animals, preventing concurrent analysis of neurovascular crosstalk within identical genetic/physiological contexts.
New Methods: We developed an enzymatic digestion/bovine serum albumin density gradient technique that enables the simultaneous isolation of neural tissue and microvascular segments from individual mice. The neural tissue was filtered and centrifuged for primary cortical neuron culture on poly-L-lysine-coated plates.

The common parasite Toxoplasma gondii can infect all warm-blooded animals, including humans. Although most infections in humans remain asymptomatic, clinical toxoplasmosis can develop into a fatal disease. Infections are usually contracted by oral ingestion of tissue cysts or oocysts contained in cat feces.

While Dynamic Flux Balance Analysis provides a powerful framework for simulating metabolic behavior, incorporating operating conditions such as pH and temperature, which profoundly impact monoclonal antibodies production, remains challenging. This study presents an advanced dFBA model that integrates kinetic constraints formulated as functions of pH and temperature to predict CHO cell metabolism under varying operational conditions. The model was validated against data from 20 fed-batch experiments conducted in Ambr®250 bioreactors.

The walls of all embryonic, foetal, and adult blood vessels contain mesodermal progenitors, distributed as pericytes in capillaries and micro vessels, and fibroblastic cells in the tunica adventitia of larger veins and arteries. Following dissociation, selection by flow cytometry, and culture, those perivascular cells turn into bona fide mesenchymal stem cells of which they possess all attributes. In vivo, the adventitial cellular niche supports several spatially-organized subsets of mesodermal progenitors biased toward either osteo-, adipo-, or fibrogenesis, and dominated by more primitive, multi-lineage stem-like cells.
