MeSH headings : 25-Hydroxyvitamin D3 1-alpha-Hydroxylase / genetics; 25-Hydroxyvitamin D3 1-alpha-Hydroxylase / metabolism; Animals; Animals, Newborn; Bone Density; Bone Development; Bone and Bones / chemistry; Calcitriol / blood; Calcium / blood; Calcium / deficiency; Calcium, Dietary / administration & dosage; Cell Differentiation; Cell Proliferation; Cells, Cultured; Female; Gene Expression Regulation; Male; Mechanical Phenomena; Mesenchymal Stem Cells / cytology; Mesenchymal Stem Cells / metabolism; Nutritional Status; Parathyroid Hormone / blood; RNA, Messenger / metabolism; Receptors, Calcium-Sensing / genetics; Receptors, Calcium-Sensing / metabolism; Sus scrofa
TL;DR: The results indicate that neonatal Ca nutrition is crucial for bone integrity and suggest that early-life Ca restriction may have long-term effects on bone integrity via programming of MSC. (via Semantic Scholar)

2009 journal article

Expression of Proinflammatory Cytokines by Human Mesenchymal Stem Cells in Response to Cyclic Tensile Strain

JOURNAL OF CELLULAR PHYSIOLOGY, 219(1), 77–83.

By: R. Sumanasinghe*, T. Pfeiler*, N. Monteiro-Riviere n  & E. Loboa*

Contributors: R. Sumanasinghe*, T. Pfeiler*, N. Monteiro-Riviere n  & E. Loboa*

MeSH headings : Animals; Bone Marrow Cells / cytology; Bone Marrow Cells / physiology; Cells, Cultured; Cytokines / metabolism; Humans; Interleukin-1beta / metabolism; Interleukin-6 / metabolism; Interleukin-8 / metabolism; Male; Mesenchymal Stem Cells / cytology; Mesenchymal Stem Cells / metabolism; Stress, Mechanical; Stress, Physiological; Tensile Strength; Tumor Necrosis Factor-alpha / metabolism; Young Adult
TL;DR: IL‐6 and IL‐8 expressions by hMSCs were induced by cyclic tensile strain and osteogenic differentiating media, indicating that IL‐ 6 andIL‐8 may be functioning as autocrine signals during osteogenic differentiation of h MSCs. (via Semantic Scholar)

Finite element modeling of 3D human mesenchymal stem cell-seeded collagen matrices exposed to tensile strain

JOURNAL OF BIOMECHANICS, 41(10), 2289–2296.

By: T. Pfeiler n, R. Sumanasinghe n & E. Loboa n

author keywords: uniaxial tensile strain; HMSCs; collagen; bioreactor; finite element modeling
MeSH headings : Biomechanical Phenomena / methods; Bioreactors; Cell Lineage; Cells, Cultured; Collagen / chemistry; Cytoskeleton / metabolism; Finite Element Analysis; Humans; Mesenchymal Stem Cells / cytology; Models, Theoretical; Pressure; Stress, Mechanical; Tensile Strength; Tissue Engineering / methods
TL;DR: Finite element models were created to evaluate the local loading conditions on bone marrow-derived hMSCs seeded in three-dimensional collagen matrices exposed to cyclic tensile strain and it was determined that globally applied uniaxial tensile strains of 10% and 12% resulted in local strains up to 18.3% and 21.8%, respectively.
