June 5 (Reuters) - U.S. stock index futures edged up on Wednesday as investors strengthened bets for an imminent start to rate cuts by the Federal Reserve, after a slew of reports signaled a weakening labor market and slowing growth in the world's largest economy.

A late rally saw Wall Street ending Tuesday's session slightly higher, paring earlier losses, with rate-sensitive real estate stocks and consumer staples leading sector gains.

Investors now await the nonfarm payrolls report, due Friday, for a comprehensive evaluation of the labor market. Surveys on the services sector from S&P Global and the Institute for Supply Management, due later on Wednesday, will also be closely watched.
