The Nasdaq market halted trading in Artes Medical this morning, with the last price of the company’s stock at 3 cents a share. In a short statement, Nasdaq said trading will remain halted until Artes has fully satisfied the electronic market’s request for additional information. Nasdaq did not describe the information it’s requested. As Ryan reported last week, Artes has filed for bankruptcy liquidation. The company, which makes injectible filler for smoothing skin wrinkles, cited the downturn in the economy and a lack of consumer spending on its cosmetic treatment.
