You haven't mentioned if there are any ethical concerns with this new meat; e.g. environmental cost of the production process, what kind of human labour is required to create it, who is providing that labour and under what conditions are they working.
Provided I had no ethical concerns with it, sure, but a lot of modern innovations tend to have these issues and I assume lab-grown meat would have these issues too.
Edit: Also, I'm opposed to animal captivity, so if there's an ongoing need to collect samples from captive livestock then no, I wouldn't. If it's a "collect it once then it keeps reproducing from the lab samples forever" type of thing then sure.
