Thyroid Hormone Receptors in Two Model Species for Vertebrate Embryonic Development: Chicken and Zebrafish

Figure 3

Expression of TRαA and TRβ in whole zebrafish embryos during the first three days post fertilisation. Specific mRNA levels were measured by qRT-PCR and normalised against the housekeeping gene Elongation factor 1α. Values represent the mean ± SEM for 3 independent samples (pools of 50–100 embryos) per stage. The arrow indicates the average time of hatching. HPF: hours post fertilisation. Data were taken from [7, 25].
