Osteocytes and Weightlessness [PDF]

Current Osteoporosis Reports, 2021
Abstract Purpose of Review Osteocytes are considered to be the cells responsible for mastering the remodeling process that follows the exposure to unloading conditions. Given the invasiveness of bone biopsies in humans, both rodents and in vitro culture systems are largely adopted as models for studies in space missions ...

Osteocyte Mechanobiology [PDF]

Current Osteoporosis Reports, 2017
Over the past decades, osteocytes have emerged as mechano-sensors of bone and master regulators of bone homeostasis. This article summarizes latest research and progress made in understanding osteocyte mechanobiology and critically reviews tools currently available to study these cells.Whereas increased mechanical forces promote bone formation ...

Osteocyte apoptosis [PDF]

Bone, 2013
Apoptotic death of osteocytes was recognized over 15 years ago, but its significance for bone homeostasis has remained elusive. A new paradigm has emerged that invokes osteocyte apoptosis as a critical event in the recruitment of osteoclasts to a specific site in response to skeletal unloading, fatigue damage, estrogen deficiency and perhaps in other ...

Strain uses gap junctions to reverse stimulation of osteoblast proliferation by osteocytes [PDF]

, 2017
Identifying mechanisms by which cells of the osteoblastic lineage communicate in vivo is complicated by the mineralised matrix that encases osteocytes, and thus, vital mechanoadaptive processes used to achieve load‐bearing integrity remain unresolved. We

Osteocyte Cellular Senescence [PDF]

Current Osteoporosis Reports, 2020
Senescent cells are now known to accumulate in multiple tissues with aging and through their inflammation (the senescence-associated secretory phenotype, SASP) contribute to aging and chronic diseases. Here, we review the roles of senescent osteocytes in the context of bone loss.Numerous studies have established that senescent osteocytes accumulate in ...

Single cell cortical bone transcriptomics define novel osteolineage gene sets altered in chronic kidney disease

Frontiers in Endocrinology, 2023
IntroductionDue to a lack of spatial-temporal resolution at the single cell level, the etiologies of the bone dysfunction caused by diseases such as normal aging, osteoporosis, and the metabolic bone disease associated with chronic kidney disease (CKD ...

Osteocytes as a record of bone formation dynamics: A mathematical model of osteocyte generation in bone matrix [PDF]

, 2014
The formation of new bone involves both the deposition of bone matrix, and the formation of a network of cells embedded within the bone matrix, called osteocytes.

Osteocyte: a Cellular Basis for Mechanotransduction in Bone

Journal of Biomechanical Science and Engineering, 2007
Osteocyte is the most abundant cell type in bone, and the only cell type located inside the mineralized matrix. The striking structural design of bone predicts an important role for osteocytes in determining bone structure and function.

The Mechanosensory Role of Osteocytes and Implications for Bone Health and Disease States

Frontiers in Cell and Developmental Biology, 2022
Bone homeostasis is a dynamic equilibrium between bone-forming osteoblasts and bone-resorbing osteoclasts. This process is primarily controlled by the most abundant and mechanosensitive bone cells, osteocytes, that reside individually, within chambers of

Osteocyte-Driven Downregulation of Snail Restrains Effects of Drd2 Inhibitors on Mammary Tumor Cells [PDF]

, 2018
While bone is a frequent target of breast cancer-associated metastasis, little is known about the effects of tumor-bone interactions on the efficacy of tumor-suppressing agents.
