Nonmyelinating Schwann Cells Maintain Hematopoietic Stem Cell Hibernation in the Bone Marrow Niche

, 2011
SummaryHematopoietic stem cells (HSCs) reside and self-renew in the bone marrow (BM) niche. Overall, the signaling that regulates stem cell dormancy in the HSC niche remains controversial.

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Human digital Meissner's corpuscles are not doubly innervated

The Anatomical Record, EarlyView.
Abstract Recent studies have shown that murine and avian Meissner‐like corpuscles are innervated by two distinct mechanoreceptor afferents with different functional properties. In addition, there is evidence that one subpopulation of Meissner corpuscles of monkeys is doubly innervated by mechanoreceptors and nociceptors.

Neuron-schwann cell interaction in basal lamina formation

, 1982
The availability of tissue culture systems that allow the growth of nerve cells, Schwann cells, and fibroblasts separately or in various combinations now makes possible investigation of the role of cell interactions in the development of the peripheral ...

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

BMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

Engineering programmable peptide hydrogels for chronic refractory wounds: A mechanism‐driven framework

BMEMat, EarlyView.
To break the self‐perpetuating pathology of chronic wounds, we propose a mechanism‐driven engineering framework for peptide‐based hydrogels. This review elucidates a hierarchical strategy—from molecular design to intelligent, multi‐functional systems—that enables these programmable biomaterials to dynamically intervene in key pathological loops and ...

Interrelationship between Schwann cell function and extracellular matrix production

, 1983
Schwann cells that envelop axons resemble epithelial cells in that they form a cellular boundary that has a foothold on basal lamina; this lamina separates the Schwann cell-axon units from the endoneurial extracellular matrix (ECM) components.

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common
