Bioregulation of lubricin expression by growth factors and cytokines [PDF]

open access: yesEuropean Cells & Materials, 2007
Lubricin, also commonly referred to as superficial zone protein (SZP) and proteoglycan 4 (PRG4), is a multifaceted, cytoprotective glycoprotein that contributes to the boundary lubrication properties facilitating low friction levels at interfacing ...

Cell Contractile Force‐Mediated Morphogenetic Tissue Engineering via 4D Printed Degradable Hydrogel Scaffolds

open access: yesAdvanced Science, EarlyView.
Through the actuation of cell contractile forces, geometrically complex structures are formed via a bioprinted, rapidly degrading cell‐laden hydrogel system, resulting in cell‐only condensation within a few days of culture. This system supports stem cell differentiation down different lineages and new tissue formation, such as chondrogenesis and ...

Mitochondria‐Localized Nestin Protects Mesenchymal Stem Cells from Senescence by Maintaining Cristae Structure and Function

open access: yesAdvanced Science, EarlyView.
Nestin localizes to the mitochondrial IMS through its MTS and the TOM20 import machinery. Within the mitochondria, Nestin interacts with Mic60 via its C‐terminal Tail3 domain. Loss of mitochondrial Nestin disrupts cristae architecture, leading to mitochondrial swelling, bioenergetic dysfunction, and ultimately the senescence of hMSCs.

Regulation of ferroptosis in osteoarthritis and osteoarthritic chondrocytes by typical MicroRNAs in chondrocytes

open access: yesFrontiers in Medicine
Osteoarthritis (OA) is a progressive degenerative disorder impacting bones and joints, worsened by chronic inflammation, immune dysregulation, mechanical stress, metabolic disturbances, and various other contributing factors. The complex interplay of cartilage damage, loss, and impaired repair mechanisms remains a critical and formidable aspect of OA ...

A Novel Therapeutic Strategy for Bone Marrow Failure: Niche Rejuvenation Using Costal Cartilage‐Derived Stem Cells

open access: yesAdvanced Science, EarlyView.
CDSCs exhibit the potential to differentiate into endothelial cells, vascular pericytes, and osteoblasts. These differentiated cells are capable of secreting additional pro‐hematopoietic cytokines. Furthermore, CDSCs can inhibit apoptosis and reduce DNA damage in injured hematopoietic stem and progenitor cells (HSPCs, including RHSCs and RHPCs), while ...

Smart Gated Hollow Mesoporous Silica Hydrogel for Targeting Endoplasmic Reticulum Stress and Promoting Periodontal Tissue Regeneration

open access: yesAdvanced Science, EarlyView.
The hollow mesoporous silica loaded with quercetin (HM‐QU@PEG) is combined with a thermosensitive anti‐bacterial matrix (TF127) to prepare HQUP@TF127. HQUP@TF127 effectively eliminates excessive ROS, alleviates endoplasmic reticulum stress, relieves mitochondrial calcium overload, and blocks the p53‐dependent apoptotic cascade. Furthermore, it enhances

Comparative Cochlear Transcriptomics in Echolocating Bats and Mouse Reveals Hras as Protector Against Noise‐Induced Hearing Loss

open access: yesAdvanced Science, EarlyView.
Comparative cochlear transcriptomics of noise‐exposed bats (Miniopterus fuliginosus) and mice reveals bat‐specific protection mechanisms for noise‐induced hearing loss (NIHL), identifying Hras as a key hub regulator. Functional studies in mice show hair‐cell‐specific Hras overexpression significantly reduced hair‐cell damage and NIHL by activating the ...
