I have some of these options in my 403(b). The particular mutual funds that are offered will vary according to the contract your institution set up.
Generally TIAA-CREF and Fidelity are good options. I have my 403(b) money spit between both. In my plan, the TIAA-CREF has good options in TIAA Traditional (interest now 4%, I use it for some of my bond allocation) and TIAA real estate. The CREF has a good international index fund and an SP500 index fund (check the expense ratios for these in your plan; they vary according to the institution.
My Fidelity fund has Spartan index funds which have low expense ratios on par with Vanguard.
If you have a 403(b), you may also have a 457 plan available that will allow you to set aside an additional 18K tax-free if you have room for that.
