Single‐Nucleus RNA Sequencing Identifies CREM as a Brake on Myofiber Hypertrophy in Chickens

Advanced Science, EarlyView.
Single‐nucleus RNA sequencing on 91 144 nuclei from postnatal chicken pectoralis major between fast‐growing broilers (FG) and slow‐growing layers (SG) identifies the transcriptional factor CREM as a novel brake of myofiber hypertrophy. Mechanistically, functional validation experiments confirm that CREM activates the promoter of JUN and CREM deletion ...

Aging Schwann cells in vitro

European Journal of Cell Biology, 2007
Schwann cells (SCs) can support the regeneration of lesioned fiber tracts of the peripheral and central nervous system and have been transplanted alone or in combination with synthetic nerve guides. For neuronal tissue engineering purposes, the cells must be isolated from small biopsies and expanded in vitro. In this study we analyze the impact of cell

Biomimetic Nanomedicine for Aging‐Impaired Bone Regeneration: From Microenvironmental Dysfunction to Precision Therapeutics

Advanced NanoBiomed Research, EarlyView.
Aging disrupts the cellular, immune, vascular, and neural processes required for bone regeneration. This review connects these pathological barriers with biomimetic nanomedicine design, highlighting strategies for cellular rejuvenation, immune modulation, vascular regeneration, and neuro–bone coupling.

The Schwann Cell

Acta Biológica Colombiana, 2004
The neurones are the cells of the nervous system and are surrounded and protected by glials cells. In the peripheral nervous system the Schwann cells (SC) are the glia of the nerves. The prolongations or neurites (axon and dendrite) of the neurones bodies are surrounded by the SC to form nervous fibers.

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.

Silencing of the Charcot–Marie–Tooth associated MTMR2 gene decreases proliferation and enhances cell death in primary cultures of Schwann cells

Neurobiology of Disease, 2007
Loss of function of the myotubularin (MTM)-related protein 2 (MTMR2) in Schwann cells causes Charcot–Marie–Tooth disease type 4B1, a severe demyelinating neuropathy, but the consequences of MTMR2 disruption in Schwann cells are unknown.

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 ...

Matrix metalloproteinase 7 promoted Schwann cell migration and myelination after rat sciatic nerve injury

Molecular Brain, 2019
Schwann cells experience de-differentiation, proliferation, migration, re-differentiation and myelination, and participate in the repair and regeneration of injured peripheral nerves.
