Good Evening JD and Leomer!

Indeed there is still a need to further elucidate the molecular mechanisms involved in the development of the inner ear. To answer your question, there are actually different approaches to do this. There are inhibitory approaches to elucidate morphogenetic pathways (Sai et al., 2014), conditional approaches to test signaling pathways (Bok et al., 2013), as well as microarray, RNA-seq, and qPCR approaches for the elucidation of proteins and other signaling pathways involved in cochlear morphogenesis (Mann et al., 2014).

We hope this answers your question and happy new year to you both as well!
