Study type | Observational |
The goal of this clinical trial is to compare the quality of mesoangioblasts isolated from various patient groups suffering from muscle atrophy. This study includes cancer cachexia and muscle-impaired elderly and a control group of the same age. The quality will be defined on these following outcomes: - The number and distribution of the mesoangioblasts in a muscle biopsy to define if there are sufficient mesoangioblasts to start a culture. - The proliferation capacity to define if we can culture them the numbers required for systemic treatment. - The myogenic capacity to define if the mesoangioblasts are sufficiently capable to generate muscle fibres. Participants will: - Undergo a muscle biopsy (needle biopsy or rest material from surgery, ~50mg) - Donate blood (~20 ml) - Fill in SARC-F questionnaire (evaluate sarcopenia score) - Fill in SQUASH questionnaire (evaluate physical activity of previous week) Researchers will compare groups (muscle-impaired elderly vs control; cancer cachexia vs control) to see if there is a difference regarding quality. These results will define the potential of autologous mesoangioblast therapy within these groups.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Number of mesoangioblasts ex vivo isolated from muscle biopsy | The number of mesoangioblasts obtained from a muscle biopsy. Once cells reached >80% confluency in a culture dish, FACS analysis will determine the amount of mesoangioblasts obtained. | 1 day | |
Primary | Proliferation capacity of mesoangioblasts in vitro | The proliferation capacity to define whether we can culture them in the numbers required for systemic treatment. Doubling time will be assessed 3 separate instances with a hemocytometer. Population doubling level = 3.32 (log viable cells at harvest - log seeded cells) | 1 day | |
Primary | Myogenic capacity of mesoangioblasts in vitro | The myogenic capacity to define if the mesoangioblasts are sufficiently capable to generate muscle fibres. Myogenic capacity is calculated as the number of nuclei in MF20-positive fibers divided by total number of nuclei per field. | 1 day | |
Primary | Distribution of mesoangioblasts in a muscle biopsy | The number of mesoangioblasts in a muscle biopsy. Histochemistry will reveal the location of the pericyte-like mesoangioblasts surrounding the blood vessels when stained for pericyte marker NG2 proteoglycan. | 1 day | |
Secondary | Homing potential of mesoangioblasts in vitro | The homing potential of the mesoangioblasts in these patients by characterizing inflammatory parameters via qPCR. Muscle damage reflected by inflammation is essential for the migration and engraftment of mesoangioblasts in the affected muscles. Differences in gene expression levels of cytokine IL6 and cytokine mediator HMGB1 in the groups MIE and Lung cancer patients vs Controls will be determined. | 1 day | |
Secondary | ATP production of mesoangioblasts in vitro | ATP production as a marker for metabolic health will be determined via the CellTiterGlo assay. Luminescence (Relative Light Unit) corrected for DNA content per well determines the ATP production. | 1 day | |
Secondary | Difference in myogenic potential of mesoangioblasts and satellite cells in vitro | Differences in myogenic potential between mesoangioblasts and satellite cells with respect due cachexia and sarcopenia. Myogenic capacity is calculated as the number of nuclei in MF20-positive fibers divided by total number of nuclei per field. | 1 day |
