Optimal cellular mechanotransduction is essential for tendon matrix homeostasis. We recently developed an in vivo rat model of tendinosis, where the plantaris tendon are overloaded through ablation of the synergistic Achilles tendon. Using this model we determined that tissue overload disrupts matrix-cell interactions, which results in under-stimulation of tendon cells (tenocytes) (Fig.1)

Using an ex vivo model of tendon stress deprivation by maintaining tail tendon fascicles in floating culture we showed that tenocyte under-stimulation results in destabilization of filamentous (F-)actin (Fig.2). F-actin destabilization coincides with tendinosis-like gene expression: downregulation of tenogenic genes (Col1, Tnc, asma, Scx), upregulation of chondrogenic (Acan, …

Introduction

Learning 3D anatomy from 2D figures can be challenging. The use of 3D printing in medical education has shown to improve knowledge and skill in surgical training⁽¹⁾. We investigated the efficacy of 3D printed coronary artery models in teaching coronary anatomy to medical students.

A Horseshoe Kidney With A Unique Constellation Of Renal Vasculature - A Case Report, Guiyan Zhang, Richard Schmidt

Department of Pathology, Anatomy, and Cell Biology Posters

Horseshoe kidney with variable vascular supply is of interest to clinicians and anatomists due to its immense surgical significance. A horseshoe kidney encountered during cadaveric dissection is reported here. The left kidney is vertical and the right kidney is slightly horizontal. The isthmus is narrow and 1.5cm inferior to the inferior mesenteric artery. The hilum of the right kidney opens anteriorly and the left opens anteromedially. The ureters lie on the anterior surfaces of both kidneys. In addition to renal arteries arising from the aorta described in previous reports, a unique renal artery (Renal Artery 3) was found supplying the …
