A computed tomography‐based survey of paramedullary diverticula in extant Aves

open access: yesThe Anatomical Record, Volume 306, Issue 1, Page 29-50, January 2023., 2023
Abstract Avian respiratory systems are comprised of rigid lungs connected to a hierarchically organized network of large, regional air sacs, and small diverticula that branch from them. Paramedullary diverticula are those that rest in contact with the spinal cord, and frequently invade the vertebral canal.

Diallyl Trisulfide From Garlic Regulates RAB18 Phase Separation to Inhibit Lipophagy and Induce Cuproptosis in Hepatic Stellate Cells for Antifibrotic Effects

open access: yesAdvanced Science, EarlyView.
Diallyl trisulfides (DATs) selectively induce cuproptosis in hepatic stellate cells (HSCs) by targeting Ras‐related protein Rab‐18 (RAB18) and regulating lipophagy. DATs promote RAB18 phase separation, enhance mitochondrial‐associated membrane structures (MAMs) formation, and increase succinylation of dihydrolipoamide dehydrogenase (DLD) at K320.

Morphologies in‐between: The impact of the first steps on the human talus

open access: yesThe Anatomical Record, Volume 306, Issue 1, Page 124-142, January 2023., 2023
Abstract Objective The development of bipedalism is a very complex activity that contributes to shaping the anatomy of the foot. The talus, which starts ossifying in utero, may account for the developing stages from the late gestational phase onwards.

PLXDC1+ Tumor‐Associated Pancreatic Stellate Cells Promote Desmoplastic and Immunosuppressive Niche in Pancreatic Ductal Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
This study uncovers the activation, heterogeneity, and regulatory roles of pancreatic stellate cells (PSCs) at single‐cell and spatial levels. It further identifies PLXDC1+ PSCs near aggressive LRRC15+ cancer‐associated myofibroblasts and SPP1+ macrophages, forming a desmoplastic and immunosuppressive tumor niche that promotes CD8+ T cell exhaustion ...

Endostructural and periosteal growth of the human humerus

open access: yesThe Anatomical Record, Volume 306, Issue 1, Page 60-78, January 2023., 2023
Abstract The growth and development of long bones are of considerable interests in the fields of comparative anatomy and palaeoanthropology, as evolutionary changes and adaptations to specific physical activity patterns are expected to be revealed during bone ontogeny.

Single‐Cell Analysis Clarifies Pathological Heterogeneity in Tenosynovial Giant Cell Tumor and Identifies Biomarkers for Predicting Disease Recurrence

open access: yesAdvanced Science, EarlyView.
MP3 tumor cells, a specific subpopulation of tumor cells in D‐TGCT, regulated the differentiation of CD34+ Fbs into MMP3+ Fbs and APOE+ Fbs through COL6A3 − (ITGAV + ITGB8) interaction. APOE+ Fbs activated IL‐1B+CCL20+ Mφs through the CXCL12/CXCR4 axis. IL‐1B+CCL20+ Mφs and MMP3+ Fbs participated in the local invasion of D‐TGCT.
