@lindahearing, I thought the Columbia study was on hiatus right now. Was your application accepted? It's part of a three institution study — Columbia, Hopkins and the University of Kansas. It's not stem cell though. It's tissue regeneration using their drug CGF166.
Here's a description of the trial from the government clinical trials website: https://clinicaltrials.gov/ct2/show/NCT02132130
There is an article in the magazine, Scientific American, "Out of the Silence" on gene therapy, December 2018 issue. Here is a quote from that article, "One main test of restored ear function involves exposing the rodents to a sudden, startling noise to see if they jump. Many did: the once deaf mice could hear."
Welcome to Connect, @navazo. I believe this is the article to which you refer:

Navazo, what is your experience with hearing loss?

Hello there. You can find a very good Katherine Bouton article talking about it on psychologytoday.
