Abstract

Bone marrow-derived human mesenchymal stem cells (BM-hMSCs) represent a promising cell-based therapy for a number of degenerative conditions. Many applications require cell expansion and involve the treatment of diseases and conditions found in an aging population. Therefore, the effects of donor age and long-term passage must be clarified. In this study, the effects of donor age and long-term passage on the morphology, proliferation potential, characteristics, mesodermal differentiation ability, and transdifferentiation potential of hMSCs towards neurogenic lineage were evaluated. Cells from child donors (0-12 years, n = 6) maintained their fibroblast-like morphology up to higher passages and proliferated in a greater number than those from adult (25-50 years, n = 6) and old (over 60 years, n = 6) donors. Adipogenic, osteogenic, and neurogenic differentiation potential decreased with age, while chondrogenic potential did not change. Long-term passage affected the morphology and proliferation of hMSCs from all ages. With increasing passage number, proliferation rate decreased and cells lost their typical morphology. Expression levels of neural markers (β III tubulin and NSE) and topo II isoforms in populations of nondifferentiated hMSCs were investigated by reverse transcription polymerase chain reaction analysis. While neural marker and topo IIβ expression levels increased due to increasing passage number in adult hMSCs compared to child hMSCs, topo IIα decreased in both. These results indicated that, even under highly standardized culture conditions, donor age and long-term passage have effects on hMSC characteristics, which should be taken into account prior to stem cell-based therapies.

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Older donors of BM-MSCs have lower osteogenic, adipogenic and neurogenic capacities.

    “with older donors of BM-MSCs having lower proliferation rates [246], [249] and osteogenic [246], [248], adipogenic and neurogenic [248] capacities.”
  • Donor age and sex can affect MSC activity and thus the properties of MSC-secretome.

    “In addition, the number of MSC passage [246], [247], [248] and the donor variability [246], [247], [248] cannot be ignored since MSC activity and, thus, the properties of MSC-secretome can be affected by donor age and sex [246], [248], [249]”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
