Digital microscope and M8 slide scanner in use Genetics research

Bin Ren et al. deal with the topic of artificial expression of bone material via adipose tissue cells in their scientific report in the scientific journal Nature, “Genes activated adipose tissue fragments as advanced autologous biomaterials for bone regeneration: osteogenic differentiation within the tissue and implications for clinical translation”. The basis for this is genetics. A specific gene, the so-called BMP-2, which is responsible for the formation of bone material, must first be integrated into the fat cells. This is done via adeno-associated viruses, which act as a smuggler of genetic material. Once in the cell nucleus, this strand is to be read with the BMP-2 and thus the desired molecule is to be produced, which later leads to bone formation. The presence of the molecule, the hBMP-2, was quantitatively checked by various optical tests.

Result: Our M8 microscope was used in this process to take scans for histomorphometry and immunohistochemical staining.

Digital microscope and M8 slidescanner used for pathology teaching

Due to the Covid-19 pandemic educations in medicine was facing new challenges, because of social distancing and new hygiene standards. With digitalization, education should overcome these challenges and because of these sudden changes, the process to come in to digital working was pushed forward very fast. Farinawati Yazid et al. published a study where they observed „The Use of Digital Microscope in Oral Pathology Teaching” by using our M8.

Result: Our digital microscope was used for scanning different slides on that the students could do the practical learning. We are proud that our microscope was part of this study. The digital transformation is a big step to overcome several challenges not only with Covid-19 but also challenges in distances coming with ongoing globalization and other problems that can be solved by digital solutions.

M8 Microscope and Scanner Used in Research on ZIF-8 Sericin Hydrogel for Bone Regeneration Promoting Angiogenesis and Osteogenesis

A recent study used the M8 microscope and scanner to evaluate a novel bone regeneration scaffold. Designing scaffolds with optimal biodegradability, osteogenic potential, and angiogenic properties presents a significant challenge. Thymosin beta 10 (TMSB10), known for its roles in angiogenesis and osteogenic differentiation, faces activity preservation limitations. To address this, researchers engineered ZIF-8 as a carrier for TMSB10 (TMSB10@ZIF-8), integrating it into a self-assembled sericin hydrogel. Testing the composite in a rat cranial defect model revealed successful synthesis of TMSB10@ZIF-8 with an 88.21% encapsulation efficiency. The sustained release of TMSB10 from this composite significantly enhanced tube formation in HUVECs and promoted angiogenesis in the CAM model. Additionally, it notably improved osteogenic differentiation in MC 3 T3-E1 cells. Eight weeks post-implantation, the TMSB10@ZIF-8/Sericin hydrogel group demonstrated substantial bone healing (86.77 ± 8.91%), outperforming controls.

Result: Histological observation of the skulls was conducted using M8 microscope and scanner. The skulls were first decalcified, followed by dehydration using a graded series of ethanol. Subsequently, the samples were cleared in xylene and embedded in paraffin. Tissue slices were then obtained from the central area of each defect and subjected to staining with H&E, Masson\'s trichrome, and Sirius Red for microscopic evaluation. The approach enabled detailed examination and documentation of tissue morphology and composition within the bone defects, providing crucial insights into the efficacy of the TMSB10@ZIF-8/Sericin hydrogel scaffold in promoting bone regeneration.

Research Uses ViewPoint Software to Quantify Glial Changes and Corpus Callosum Dimensions in Anorexia Nervosa Mice Models

Using the software ViewPoint, a study on anorexia nervosa (AN) revealed emaciation and neuropsychological deficits, with observed brain atrophy. This study on chronically starved mice explored glial changes in the corpus callosum (CC) and hypothalamus, critical in feeding regulation. Immunohistochemistry revealed decreased densities of OLIG2+ oligodendrocytes, GFAP+ astrocytes, and IBA1+ microglia in the CC after chronic starvation. However, glial densities in the arcuate nucleus (ARC), a key feeding center, remained unchanged. Notably, neuropeptide Y (NPY) staining intensity increased, suggesting heightened orexigenic signaling. These findings propose a role for glial pathophysiology in AN, particularly in CC alterations during chronic starvation.

Result: GFAP staining utilized sections at Bregma − 1.12 mm, whereas IBA1 and OLIG2 staining used sections at Bregma − 1.54 mm. Two immunohistochemically stained sections were digitized for each analysis, with averaged results. ViewPoint software was used to quantify GFAP+, IBA1+, and OLIG2+ cell numbers, assessed by two blinded evaluators, and presented as cells per mm2. Counting included cells with visible nuclei. Corpus callosum (CC) measurements, taken in three regions, were averaged, excluding damaged regions. This meticulous approach ensured accuracy in evaluating glial markers, cellular distribution, and CC dimensions in the designated brain sections.
