Background: The definitive treatment of Kienbock's disease has yet to be determined. Wrist denervation combined with core decompression of the radius has not been previously studied as a combined treatment for Kienbock's disease.

Purpose: The purpose of this study was to assess the efficacy of simultaneous wrist denervation and core decompression of the radius in the treatment of Kienbock's disease.

A major challenge in the stem cell biology field is the ability to produce fully functional cells from induced pluripotent stem cells (iPSCs) that are a valuable resource for cell therapy, drug screening, and disease modelling. Here, we developed a novel inducible CRISPR-mediated activation strategy (iCRISPRa) to drive the expression of multiple endogenous transcription factors (TFs) important for in vitro cell fate and differentiation of iPSCs to haematopoietic progenitor cells. This work has identified a key role for IGFBP2 in developing haematopoietic progenitors.

The CRISPR/Cas9 system has transformed genome editing by enabling precise modifications for diverse applications. Recent advancements, including base editing and prime editing, have expanded its utility beyond conventional gene knock-out and knock-in strategies. Additionally, several catalytically dead Cas9 (dCas9) proteins fused to distinct activation domains have been developed to modulate endogenous gene expression when directed to their regulatory regions by specific single-guide RNAs.

Erythroblastic island (EBI) macrophages play an essential role in the production and maturation of the vast numbers of red blood cells (RBCs) that are produced throughout life. Their location within the bone marrow makes it difficult to study the cellular and molecular interactions associated with their action so we have used an model of the EBI niche using macrophages derived from human induced pluripotent stem cells (hiPSCs). We previously demonstrated that the activation of the transcription factor KLF1 enhanced the activity of hiPSC-derived EBI macrophages.

Article Synopsis
  • Rotator cuff injuries happen a lot in the U.S., leading to over 500,000 surgeries each year, but many do not work as well as hoped.
  • A special tissue called the subacromial bursa, which sits near the rotator cuff, seems to help with injury healing and might need to be kept during surgeries.
  • Research in rats showed that the bursa helps protect nearby tendons and promotes healing, and it might also be useful for delivering medicine to reduce pain and inflammation in damaged tendons.
