Cerebrovascular Laboratory

Stroke is a major cause of morbidity and mortality in the U.S. population, particularly among aged individuals. Current demographic projections suggest that as the elderly population continues to expand, the need for developing improved treatment options for stroke patients will become even more pressing. Our lab is interested in the molecular events that occur during focal ischemia and in the use of stem cell approaches to improving neurological outcomes following stroke. Our main experimental model involves middle cerebral artery occlusion (MCAO) to generate focal ischemia in spontaneously hypertensive rats (SHR).

Over the past several years, we have differentiated green fluorescent protein-expressing human embryonic stem cells (GFP-hESC) into mesenchymal stem cell-like cells (eMSCs). These eMSCs expressed markers (CD-29, CD-44, CD-73, CD-105, CD-166 and Nestin, but not CD-34, C45, CD-106, SSEA-4 or Oct-4) which are consistent with a mesenchymal stem cell state. We have transplanted eMSCs into the femoral veins of SHRs following MCAO. The expression of GFP allows us to follow the migration and further differentiation of the eMSCs in the ischemic brain. We observed migration of the injected eMSCs to the infarction region (Fig. 1) and their subsequent differentiation into neurons (which expressed β-tubulin III, MAP2, HuC and neurofilament) (see Fig. 2) and vascular endothelial cells (which expressed vWF; see Fig. 3). The grafted cells do not appear to differentiate into astrocytes.

Figure 1Figure 1: Human ES cell-derived mesenchymal stem cells (eMSCs) expressing green fluorescent protein were injected into the femoral vein of rats two days after induction of stroke via middle cerebral artery occlusion. Injected eMSCs migrated to the brain and were found not only in the infarction core (A), but also in the ischemic penumbra as well as remote regions such as cortex and striatum (B, C, D).  eMSCs did not migrate to the contralateral hemisphere (E, F). No GFP-positive cells were observed in the infarction (G) or penumbra (H) regions of PBS-injected control rats.
Figure 2: A subset of transplanted eMSCs (staining positive for GFP and human nuclear antigen) showed evidence of neuronal differentiation (indicated by b tubulin III staining in “Neural Marker” panel) in triple-stained brain sections from the ischemic infarction region two days after injection. Arrows indicate triple-stained cells. (Bar=100µm). Figure 2

Figure 3Figure 3: A subset of transplanted eMSCs (GFP+) showed expression of the endothelial cell marker, von Wildebrand factor (vWF) by 1 week after injection. At 2 weeks, vWF and GFP double-positive cells were observed to form vascular channels. White arrows indicate co-localization of GFP and vWF at 1 week and 2 weeks after transplantation. (Bar=100µm). (vWF positivity was not detected at day 2 after cell transplantation.)

The injected cells survived in the infarction region for at least four weeks after infusion. The infarction volume at 4 weeks post-MCAO was significantly reduced in eMSC transplant recipients relative to that in brains from rats that received only PBS injection. Importantly, post-ischemic behavioral functioning significantly improved in transplant recipients. In these experiments, we found that the engrafted cells did not survive beyond ~4 weeks. The loss of transplanted cells from the infarction region after 4 weeks occurred despite the use of cyclosporin A to suppress the immunological response. We are therefore seeking ways to improve engrafted cell survival in order to enhance the neurogenesis and angiogenesis of the transplanted cells and sustain or improve the neurological recovery of the whole animal. Some approaches include pre-conditioning the eMSCs in culture before transplant, engineering the stem cells to produce specific trophic factors, and treating the SH rats with dietary or pharmaceutical supplements before or after MCAO. We are also interested in determining whether other stem cell types, including induced pleuripotent (iPS) cells may offer greater neurologic protection or longer post-transplant survival.

Anatomical knowledge and microsurgical skills require comprehensive laboratory training before mastering these skills. The study of anatomy goes back over thousands of years. Although we have many technological developments and diverse training models, the importance of handling and dissecting real tissues and organs, has not been changed as a way to learn anatomy. The term “dissection” means “to expose to view.” The dissection laboratory provides an introduction to the variability of the human body and the uniqueness of each cadaver. Furthermore, it is the only place where the surgeons can improve their understanding of the three-dimensional structure of the human body by visual and tactile pathways. University of Wisconsin, Lincoln Ramirez Neurosurgery Operative Skills Laboratory does not only provide neurosurgery residents and fellows to have a rare opportunity to explore anatomy using human cadavers but also gives them the chance of training in spatial appreciation and orientation and in the use of instruments that enhance their eye-hand coordination and manual dexterity. The laboratory is equipped with four fully functional stations that can be used for microdissections simultaneously. Each station has its own set of neurosurgical equipment including an operating microscope, suction, and drills. Whatsmore, in total, there are 8 downdraft tables which can be used as 16 skull-base surgery stations. At each learning stations, residents and fellows can explore and learn anatomy under the tutelage of a teaching assistant. Since the use of formalin is allowed in the lab because it has an adequate ventilation system and downdraft tables, the lab can be used for skull-base surgery courses, spinal and peripheral nerve surgery courses. The lab allows for recording video and still images while performing surgical procedures. In the demonstration station, a faculty performs the specific surgical approach, and the microscopic view (the magnified view of the operative field) is showed in two big screens. The faculty’s position and movements are shown in another big screen. The laboratory is reserved not only for the use of the residents, fellows, and attending staff of the department of neurological surgery, but also it provides excellent collaborations with the other surgical departments in the education field. The Lincoln Ramirez Neurosurgery Operative Skills Laboratory is directed by Dr. Mustafa Baskaya, MD.
