The objective of this study was to determine how initial chondrocyte density in an alginate hydrogel affects the matrix composition, its distribution between the cell-associated (CM) and further removed matrix (FRM) fractions, and the tensile mechanical properties of the developing engineered cartilage.
Fraction C was again chromatographed on Sephadex LH-20 (column 4 × 90 cm) and further on silica gel (column, CH2Cl2) to afford a mixture of the unstable compounds 2 and 3 (35 mg).
First, FP disks (150 mm in diameter, Whatman grade 1; Whatman Inc, Piscataway, NJ, USA) were cut into 1-cm × 6-cm strips and further trimmed to a final weight of 50.0 ± 0.1 mg for each strip.
About 60 70 % of the incident light was received at the water surface (2.5 cm), but it decreased to ∼40 50 % at 50-cm depth and further to 20 30 % at 100 cm.
The chromosomal regions identified with this approach are large, typically 20 40 cM [1], and further work is therefore needed to pinpoint the specific gene(s) and causal mutation(s) responsible for the QTL effect.
Saos-2-Mock, Saos-2Tet-p53-WT, -S121F, and -R175H cells were grown to 70 80% confluence in 6-cm dishes and further incubated with or without Dox for 24 h.
Our analyses show that the superficial application of this lime by-product had (Tables 3 and 4), in the short term, a limited effect on the soil pH of the epipedon (rather concentrated in the top −10 cm and weaker further down, i.e., 10 20 cm).
The genomic DNA was extracted from the mycelium cultivated in CM and was further purified using a DNeasy Plant Mini Kit (QIAGEN, Hilden, Germany).
Normal mucosa samples were harvested upstream (proximal) and downstream (distal) to the freshly resected tumours at 1 cm intervals for at least 5 cm, and at further intervals (in long specimens) until both resection margins were reached.
Non-adherent cells were transferred to 10 cm petri dishes and further cultured in the presence of M-CSF (30 ng/mL) for 3 days.
