Is Cord Blood Banking Tax Deductible?

I was reading an article on whether cord blood banking is tax deductible. If you itemize expenses on your 1040 form, you can claim a deduction for any medical expense which exceeds 7.5 percent of your Adjusted Gross income. To help you figure out what is and is not deductible, the IRS publication number 502 titled "Medical and Dental Expenses" will give you a listing of allowed deductions. This publication makes no mention of cord blood banking. I wonder if any of the tax experts have an opinion on whether cord blood banking is tax deductible?
