Display regions in user-profile.tpl.php
For anyone wondering about this, here's how to do it (code goes in your theme's template.php file):

function YOUR_THEME_preprocess_user_profile(&amp;$variables) {
  $variables['YOUR_NODE_REGION'] = block_get_blocks_by_region('YOUR_NODE_REGION');
}


And then in your user-profile.tpl.php template:

&lt;?php if ($YOUR_NODE_REGION): ?&gt;
  &lt;div class="custom-region"&gt;
    &lt;?php print render($YOUR_NODE_REGION); ?&gt;
  &lt;/div&gt;
&lt;?php endif; ?&gt;
