If you were wondering how #dental #enamel resists years of damage and wear, the "enamel rods" are tightly packed, long structures composed of hydroxy(l)apatite nanowires. This highly organized pattern of enamel rods achieves exceptional durability and resistance to mechanical stress.

Apparently it has been known since 1975 that #collagen fibrils in #bone are violent and unruly! 🤣

#Apatite is also a timelord ! Decaying uranium 238 creates fission tracks; the number in a crystal is used to measure the time since the formation of the apatite grain! #Mincup23

Alien invasion!!! 👾 👽 Under in vitro culture, a #human #mesenchymal #stemcell crawls into an #osteocyte lacuna (http://bit.ly/Osteocyte) at the #bone surface, observed by scanning #electron #microscopy 🔬 🦴 Forget shape-memory #alloys! #Cells remember! (Arrowheads = bone #mineral)

Here's a transmission electron microscopy (TEM) image of #bone showing mineralized #collagen and an #osteocyte lacuna containing microcalcifications of #apatite and #whitlockite.

Such #calcification or #mineral formation is part of normal physiological processes such as #apoptosis but can also indicate #pathology.

The specimen was prepared using focussed ion beam scanning electron microscopy (FIB-SEM).
