How to format certain words of a cell's text label

I have a xamarin iOS project where I am displaying a cell with x lines of text. I currently define my cells like so:

public override UITableViewCell GetCell (UITableView tableView, Foundation.NSIndexPath indexPath)
    {
        UITableViewCell cell = tableView.DequeueReusableCell ("cells");
        ...
        cell.TextLabel.Lines = 0;
        cell.TextLabel.Text = "Bold: " + info1 + "Bold: " + info2;

        ...
    }

Which displays the cell like:

   +----------------------+
   |Bold: Testing         |
   |Bold: Testing2        |
   +----------------------+

I want to be able to turn just the Bold text to the bold font and keep the other info in normal text font. Is this possible given my current approach?
