Semin Neurol 2018 Dec 6;38(6):640-643. Epub 2018 Dec 6.

Department of Neurology, Boston University School of Medicine, Boston, Massachusetts.

Myofascial pain syndromes arise from acute and chronic musculoskeletal pain and often have a referred neuropathic component. It affects more than three quarters of the world's population and is one of the most important and overlooked causes of disability. The origins of pain are thought to reside anywhere between the motor end plate and the fibrous outer covering of the muscle, with involvement of microvasculature and neurotransmitters at the cellular level.

Surgical adhesions in mice are derived from mesothelial cells and can be targeted by antibodies against mesothelial markers.

Sci Transl Med 2018 Nov;10(469)

Comprehensive Pneumology Center, Institute of Lung Biology and Disease,Helmholtz Zentrum München, Member of the German Center for Lung Research (DZL), Munich, Germany.

Peritoneal adhesions are fibrous tissues that tether organs to one another or to the peritoneal wall and are a major cause of postsurgical and infectious morbidity. The primary molecular chain of events leading to the initiation of adhesions has been elusive, chiefly due to the lack of an identifiable cell of origin. Using clonal analysis and lineage tracing, we have identified injured surface mesothelium expressing podoplanin (PDPN) and mesothelin (MSLN) as a primary instigator of peritoneal adhesions after surgery in mice.

Self-assembling peptides (SAPs) are synthetic bioinspired biomaterials that can be feasibly multi-functionalized for applications in surgery, drug delivery, optics and tissue engineering (TE). Despite their promising biocompatibility and biomimetic properties, they have never been considered real competitors of polymers and/or cross-linked extracellular matrix (ECM) natural proteins. Indeed, synthetic SAP-made hydrogels usually feature modest mechanical properties, limiting their potential applications, due to the transient non-covalent interactions involved in the self-assembling phenomenon.
