Advancing Stem Cell Research with Quantitative Live Cell Imaging

Stem cells are extremely sensitive and vulnerable to fluorescent labeling or strong laser power. The HoloMonitor live cell imaging system uses non-invasive digital holography to monitor stem cells without the need for any toxic labeling or staining. Therefore, you can image your precious stem cells for as long as you want in their native state.

Quantify the morphological and migratory characteristics in MSCs

HoloMonitor is a novel live cell analysis tool and provides accurate quantification of morphological and migratory characteristics including cell area, thickness, migration speed and distance.

In this study, the authors compared human periosteum and donor-matched iliac crest bone marrow multipotential stromal cell (BM MSC) using the HoloMonitor single cell tracking and kinetic morphology assay. Also, they use the data to define the development of novel bone graft substitutes to be repopulated by MSCs.

Study synergistic effects between KLF2+ hMSCs and HUVECs in bone regeneration

Mesenchymal stem cells (MSCs) are undifferentiated stem cells with the potential to differentiate into multiple lineages and are widely used as cell sources in bone tissue engineering. In addition, the co-culture of MSCs with endothelial cells (ECs) has attracted a great deal of interest in the development of strategies to achieve vascularized bone in recent years.

In this publication, the authors identified Krüppel-like Factor 2 (KLF2) as a marker of MSCs related to stemness. Moreover, the results showed that KLF2+ MSCs promoted angiogenesis of human umbilical vein ECs (HUVECs), influenced its migration speed via secretion of angiogenic factors and showed an osteogenic differentiation effect.

Study osteoporosis and adipogenesis

Understanding the processes of osteogenesis
and adipogenesis of the bone marrow is remarkably important in stem cell research.

In order to get a deeper insight into the delicate equilibrium between osteogenic and adipogenic differentiation and trans-differentiation at the population level, the authors use HoloMonitor to extract quantitative biological state indicators including the average thickness (T), and the roughness kurtosis (RK) to produce a scatter plot with full osteoblasts, full adipocytes and undifferentiated hBM-MSC. Then, this T-RK plot could be in principle generalized and exploited to evaluate at a glance the effect of specific treatments or culture conditions on hBM-MSC differentiation and osteo-adipo homeostasis.
