Synthetic matrix for controlled cell ingrowth and tissue regeneration and endometriosis

The biological material comprises from the three - dimensional polymer is at least one first and second of precursor compound obtained. The first precursor is molecule comprising the molecular weight is substantially similar at least three has at least three functions polymer component and second precursor compound is at least a functional component. First and second precursor to the equivalent ratio of functional group is at 0.9 to 1.1. The precursor to the molecular weight, equipped with the molecular weight of more of nitrogen and precursor molecule method of the selective, an polymer network water content of the water absorbing completes polymer network total weight of the balance is wt%-92wt%. The invention taught the improved can be used for and/or the application the method for synthesizing substrate.
