Abstract

Fundamentals of Bone Formation In vitro models can help guide research for tissue engineering or drug delivery, but the extent to which results from in vitro experiments may mimic in vivo ones will depend on the robustness of the model. For complex tissues like the extracellular matrix or bone, this means matching the chemical organization of the tissue at both the atomic scale and the structural level. Chow et al. (p. 742 ) used nuclear magnetic resonance (NMR) spectroscopy to analyze a sample on both these length scales. First an isotope-enriched mouse was produced to enhance the NMR signal. Samples from these mice were then used to study the extracellular matrix of developing bone and the calcification front during fetal bone growth.
