I

t is well known that Si-Ca-P bioceramics are promising

bioactivematerials for bone tissue engineering, particularly

for bone repair

1

. Silicon incorporation to these ceramics

may be fundamental to skeletal development stimulating

mesenchymal stem cells proliferation and differentiation to

osteoblasts

2,3

. An important characteristic of a bioceramic

designed for bone reconstruction is its open porosity with a

high area / volume ratio that facilitates the initial circulation

of biological fluids, cell migration and vascular invasion

after bone implantation

4,5

. In this work, we have processed

a Si-Ca-P ceramic using a Q-switched Nd:YAG laser,

obtaining biocompatible ceramics with 70 µm and 350 µm

homogeneously distributed interconnected pores.

In vitro

assays using

ah

MSCs showed that cells seeded onto the top

of these scaffolds could proliferate, cross the small pores and enter into big pores. So, if we use these bioceramics

in vivo

, we

could probably observe how the cells penetrate into the bioceramics through the pores, improving the cellular and vascular

colonization of the biomaterial and allowing initial circulation of the body fluids from the first moment of implantation,

increasing the bioceramic biodegradability.

Biography

Ruben Rabadan (PhD) is a post-doctoral researcher who has his expertise in Tissue Repair, and passion in improving the health by the study of Organ and Tisse

Regeneration. In his short career, he has focused in bone, ligament and cartilage regeneration, and he has helped to develop scaffolds based on the C2S-TCP

phase diagram and combinating bioceramics with fibroin, specially testing their biocompatibility and osteointegration by

in vitro

and

in vivo

studies.
