Atomic layer deposition of TiO2 thin films on nanoporous alumina templates: Medical applications

JOM, 61(6), 12–16.

By: R. Narayan n, N. Monteiro-Riviere n, R. Brigmon*, M. Pellin* & J. Elam*

TL;DR: Atomic layer deposition was used to coat all the surfaces of a nanoporous alumina membrane in order to reduce the pore size in a controlled manner, and neither the 20 nm nor the 100 nm TiO2-coated nanoporus alumina membranes exhibited statistically lower viability compared to the uncoated nano-structure-based membrane control materials.

Osteogenic Effects of Rest Inserted and Continuous Cyclic Tensile Strain on hASC Lines with Disparate Osteodifferentiation Capabilities

ANNALS OF BIOMEDICAL ENGINEERING, 37(5), 955–965.

By: A. Hanson n, S. Marvel n, S. Bernacki n, A. Banes n, J. Aalst* & E. Loboa n

author keywords: Adipose derived stem cells; Mesenchymal stem cells; Osteogenesis; Mechanical effects on cells and tissues; Tissue engineering
MeSH headings : Adipose Tissue / cytology; Adult Stem Cells; Calcium / metabolism; Cell Differentiation; Cell Proliferation; Cells, Cultured; Humans; Mesenchymal Stem Cells; Models, Biological; Osteogenesis / physiology; Stress, Mechanical; Tensile Strength; Tissue Engineering / methods
TL;DR: Results showed that both continuous and rest inserted cyclic tensile strain increased the amount and rate of calcium deposition for both high and low calcium depositing hASC lines as compared to unstrained controls, suggesting that mechanical loading has a greater effect on cell lines that already have an innate ability to produce bone.
