            mRNA expression levels. Asph, Notch1, and Hes1 mRNA expression levels were measured using qRT-PCR analysis, with results normalized to 18S rRNA.
            ASPH immunoreactivity was measured using duplex ELISA, with immunoreactivity normalized to protein content. Inter-group statistical comparisons
            were conducted using one-way analysis of variance (Table 2) followed by post hoc Tukey tests. The P ≤ 0.05 are considered statistically significant.
