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)

#Magnesium #whitlockite formation in the alveolar #bone, with #bisphosphonate exposure and osteolytic #skeletal #metastasis. Scanning electron microscopy, Micro-Raman spectroscopy, and energy dispersive X-ray spectroscopy reveal Mg-rich, rhomboidal nodules (200 nm to 2.4 µm) within the lacuno-canalicular space. Mg-whitlockite formation in #osteocyte lacunae is multifactorial in #nature and suggests altered bone #biomineralization.

Through the eyes of an #osteocyte. In #bone, this is what the environment of partially embedded osteocytes (osteoblastic–osteocytes) is like!

Scanning electron microscopy has been used to observe the orientation of mineral platelets in relation to osteoblastic–osteocyte lacunae on the surface of deproteinized trabecular bone in adult sheep.

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).
