Sentence examples for in vitro aging from inspiring English sources

The optical properties of orthodontic aligners appear to vary between brands and constituent materials but deteriorate with in vitro aging in all cases.

The aim was to assess and compare absorbance and transmittance values of three types of clear orthodontic aligners before and after two cycles of in vitro aging.

This is in line with findings by Gracco et al. that both in vitro aging (artificial saliva) and in vivo wear increase the absorbance after 14 days.

This leads to in vitro aging, the accumulation of intracellular oxidative damage, and subsequently a decreased potential for proliferation and differentiation.

To further advance the knowledge in this field, hMSCs were cultured and routinely passaged on tissue-culture polystyrene to investigate the correlation between cell stiffening and differentiation potency during in vitro aging.

Hence, we set out to compare the transmittance and absorbance of various samples of clear aligners, both as received and after two 14-day cycles of in vitro aging, to determine whether they present any differences in terms of colour stability and aesthetic properties over time.

On average, MSCs from ICBM aspirates and LBFBM aspirates have both undergone 16PDs, with no apparent correlations being found between the "in vitro age" and functional outcomes for individual cultures.

We next investigated whether any observed donor-to-donor differences could be attributed to the "in vitro age" of tested cultures (measured as total PDs at P3, i.e. prior to differentiation).

Though the data indicate a lack of tumorigenic transformation coupled with increased neurite outgrowth-promoting activity after extensive SC expansion in vitro, thus suggesting better regeneration qualities, we strongly recommend that in vitro aged rat SCs (>11 passages) should not be employed for tissue engineering.

Based on this uncertainty we used in vitro aged eggs for our experiments.

To analyze whether the monitored alterations of in vitro aged eggs may represent changes that occur also in vivo, we compared eggs collected directly after ovulation to eggs squeezed from the same female 1.5 hours later.
