ANN ARBOR ? The Michigan Growth Capital Symposium Monday announced it has selected 45 companies to make presentations to potential investors in May – start ups that specialize in Information Technology, Life Sciences and Alternative Energy.

The presenting companies fall under the commercialization, A/B round, and expansion/growth rounds.

“The Midwest is realizing the potential that it has always had,” said David Brophy, director of the University of Michigan’s Center for Venture Capital & Private Equity Finance, and the host of the symposium, now in its 25th year. “Entrepreneurs are staying, universities are taking a leading role in commercialization activity, venture capital firms are becoming more numerous and available capital is increasing ? together these elements are a tremendous catalyst for emerging business activity in the Midwest.”

While symposium officials didn’t provide a complete list of the 45 presenting companies, they did provide a sampling of companies in each of the three investment-stage tracks:
