The role of the dynamic epigenetic landscape in senescence: orchestrating SASP expression

npj Aging
Senescence and epigenetic alterations stand out as two well-characterized hallmarks of aging. When cells become senescent, they cease proliferation and release inflammatory molecules collectively termed the Senescence-Associated Secretory Phenotype (SASP)

Amine‐Functionalized Chitosan/dECM Composite Promotes Cutaneous Regeneration and Hair Follicle Activation by Regulating Oxidative Stress and Inflammation

Advanced Healthcare Materials, EarlyView.
An amine‐functionalized chitosan and hydrolyzed dECM composite promotes cutaneous regeneration by modulating oxidative stress and inflammatory pathways. The material accelerates wound closure and stimulates hair follicle activation in UV‐damaged cutaneous tissue.

Estudio de células senescentes por citometría de imagen

, 2019
La senescencia celular, conocida como la detención irreversible de la división celular, puede ser inducida por agentes oxidantes y radiación ultravioleta entre otros. Las células senescentes se distinguen por una serie de rasgos morfológicos y moleculares, entre los que desataca el incremento de la actividad β-Galactosidasa lisosomal.

Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

Advanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.

Low‐Temperature Fabrication of Thymosin β4‐Loaded Soluble Microneedles to Promote Wound Healing by Specific Binding to Downregulated Immune Regulators Vsig4 and IL22rɑ2

Advanced Healthcare Materials, EarlyView.
Schematic diagram depicting the fabrication and application of thymosin β4 (Tβ4)‐loaded microneedle patches for wound treatment. The Tβ4 was loaded into chitosan (CS) and sucrose MNs under mild conditions (4°C, 65% relative humidity). The Tβ4 MN patch specifically binds to the downregulated immune regulators Vsig4 and IL22rα2, thereby accelerating ...
