Title:
Influence of glucocorticoids on the extracellular matrix and mechanosensitivity of osteoblasts.

Abstract / short description:
In the project applied for here, the influence of glucocorticoids (GCs) on the extracellular matrix (ECM) and the transduction of mechanical stimuli of mesenchymal stromal cells (MSCs) and osteoblasts will be investigated in more detail.
In our own preliminary work for this project, we have detected changes in ECM composition by GCs during osteogenic differentiation of MSCs. We hypothesize that these changes have an impact on the mechanical properties of the cells (elasticity, strength), as well as the transduction of mechanical stimuli e.g. by mechanosensitive ion channels (MSICs), which we will investigate in this project using atomic force microscopy (AFM) as well as calcium flux (Fluo-4) measurements.
Since the stimulation of osteoblasts and osteocytes by mechanical loading is essential for the maintenance of bone stability, disruption of this process by GCs may be a previously ignored cause of glucocorticoid-induced osteoporosis (GIOP).
By studying the mechanical and mechanosensory properties of the ECM in combination with proteomic and transcriptomic analyses, we aim to investigate this relationship and thereby contribute to the development of new therapeutic or preventive approaches.
