In situ SEM/EDS compositional characterization of osteocytes and blood vessels in fossil and extant turtles on untreated bone surfaces; different preservational pathways microns away

Scanning Electron Microscopy-Energy Dispersive Spectroscopy analyses performed directly on untreated fresh surfaces show that osteocytes-like in the fossil turtle bone are mostly composed of iron and manganese, which suggests a possible endogenous composition for these fossil structures.

Iron-mediated deep-time preservation of osteocytes in a Middle Triassic reptile bone
- GeographyHistorical Biology
- 2019
Brownish to rust-coloured microbodies, extracted from a Middle Triassic bone of the reptile Nothosaurus, are morphologically consistent with bone cells of present-day vertebrates and the absence of a distinct signal indicating organic molecules suggests that the original bone cells underwent autolysis or other degradative processes before or during mineralization.

Abstract: Microstructural and biomolecular preservation is reported in fossils as old as the Triassic. Such preservation suggests unusual taphonomic conditions. We collected fragments of fossil whale…
Long bone histology of the subterranean rodent Bathyergus suillus (Bathyergidae): ontogenetic pattern of cortical bone thickening
- Biology, Environmental ScienceJournal of anatomy
- 2017
This study is the first histological assessment describing the process of cortical thickening in long bones of a fossorial mammal and allows the tissues deposited during ontogeny to remain relatively intact, thus preserving an excellent record of growth.

The developing calvaria of the amphibian Xenopus tropicalis is examined by confocal, two-photon, and super-resolution imaging, and flattened osteocytes lying within a woven bone structured in lamellae of randomly oriented collagen fibers are described, suggesting that the cellular microenvironment plays a fundamental role in the induction and stabilization of osteocytic processes.

The results suggest that present models of fossilization processes may be incomplete and that soft tissue elements may be more commonly preserved, even in older specimens, than previously thought.

An extensive analysis of the osteocyte cytoskeleton is provided, based on the successful isolation of osteocytes from 16‐day embryonic chick calvariae, and two actin‐bundling proteins, alpha‐actinin and fimbrin, are identified in osteocyte processes.

A suite of new methods is introduced to further automate the measurement of bone cells and other microstructural features on histological thin sections to help reconstruct genome sizes of extinct organisms such as dinosaurs.
Osteocyte and bone structure
- BiologyCurrent osteoporosis reports

The osteocyte is the most abundant cell type of bone andrain-derived flow of interstitial fluid through this porosity seems to mechanically activate the osteocytes, as well as ensure transport of cell signaling molecules, nutrients, and waste products in order to determine the bone’s structure.

It can be supposed that the widened endings of the paralacunar canaliculi perform more important functions in conveyance, this being evident from comparisons of analogous areas in modern bone.
Osteocyte regulation of bone mineral: a little give and take
- Biology, MedicineOsteoporosis International

Osteocytes are able to liberate bone mineral by regulating osteoclast differentiation and activity in response to a range of stimuli, including bone matrix damage, bone disuse and mechanical unloading, oestrogen deficiency, high-dose glucocorticoid and chemotherapeutic agents.
