ABSTRACT
Sucessful tissue culture methods have been developed
which results in stable, long-term cell lines derived from
Taxus explants. Some of the cells lines are habituated,
that is, do not require plants hormones as supplements to
the nutrient culture medium, for long-term maintenance.
The cell lines established by use of the novel methods of
the present invention are capable of producing taxol, and
tacol-related compounds. These cell lines offer a rapidly
repriducible, continuously-available sourse for the
production of taxol and taxol-related compounds. This
production may be scaled to commercial levels by use of
the cell lines in bioreactors. The cell lines provide
screening assays for species and cultures of Taxus that
are sources of taxol and taxol-related compounds. In
addition to obtaining the same compositions as presently
directly extracted from

We claim:
1. A method for establishing a call line culture of
Taxus, said method comprising:
(a) selecting a young stem as a tissue source
for an explant;
(b) culturing the explant in callus-inducing
medium to form a callus;
(c) subculturing selected sections of the
callus to promote subclone growth;
(d) selecting a subclone to develop a cell
line; and
(e) culturing the cell line on a solid support
in maintenance medium.
2. The method of claim 1 wherein the Taxus is further
defined as Taxus media cv. Hicksii.
3. The method of claim 1 wherein the callus-inducing
medium comprises Gamborg's B5 medium supplement with
plant hormones.
4. The method of claim 3 wherein the plant hormones
are selected from a group consisting of 2,4-D, kinetin and
a combination of 2,4-D and kinetin.
5. The method of claim 1 wherein the selected
sections of callus are
selected based on the following criteria:high growth rate
compared to growth rate of other callus, lack of red
coloring, said coloring indicating the presence of
exudates which inhibit growth, presence of yellow
coloring, and friability.
6. The method of claim 1 wherein the solid support
for maintenance of the cell line comprises a membrane raft
and the maintenance medium comprises modified Gamborg's
B5 medium according to Table IV.
7. The method of claim 1 wherein the maintenance
medium comprises casain hydrolysate, glucose and fructose.
8. The method of claim 7 wherein the concentration
of glucose and fructose totals about 10-40 g/l.
9. The method of claim 1 wherein the maintenance
medium comprises a sugar selected from a group consisting

- 37 -
of sucrose, glucose and fructose, and wherein the
concentration of said sugar is about 40-80 g/l.
10. The method of claim 7 wherein the concentration
of casain hydrolysate is about 0.2-1.0 g/l.
11. A method of producing a cell suspension culture
from Taxus comprising:
(a) preparing a cell line according to claim 1;
(b) obtaining medium conditioned by growth of
the cell line supported on membrane rafts,
said medium containing cells from the cell
line in suspension' and
(c) culturing the cell suspension in shaker
flasks in the dark at a temperature of
about 24-26°C in Gamborg's medium
according to Table IV.
12. A method of producing a compound selected from
the group consisting of taxol, a precursor or intermediate
of the biochemical pathway resulting in taxol production,
and a derivative of taxol, said method comprising :
(a) culturing a cell culture according to claim
1 under conditions which allow production
of the compound; and
(b) collecting the compound from the cells in
culture or from the conditioned medium of
the culture.
13. The method of claim 12 further comprising
enhancing production of secondary metabolites of the
compounds by applying alicitation techniques.
14. The method of claim 13 wherein alicitation
techniques comprise feeding taxol precursors to the cell
cultures.
15. The method of claim 12 further comprising the
isolation and purification of taxol from non-taxol-
containing compounds and from contaminants.
16. The method of claim 12 wherein the cell
compositions are cultured in large scale bioreactors.
17. A cell line having the following
characteristics:

-38-
(a) stable growth in culture; and
(b) capability of expressing a compound
selected from the group consisting of
taxol, a precursor or intermediate of the
biochemical pathway resulting in the
production of taxol, and a derivative of
taxol.
18. The cell line of claim 17 further defined as
comprising maintaining the capability of expressing a
composition of step b, after cold storage and
reconstitution of the cell culture.
19. The cell line of claim 17 wherein Taxus
comprises Taxus media cv. Hicksii.
20. The cell line of claim 17 wherein the compound
is capable of inhibiting cell growth in cancer model
systems or of producing positive results in a microtubule-
stabilizing bioassay.
21. The cell line of claim 20 wherein the cancer
model system comprises a cell line selected from a group
consisting of ?16 melanoma, MX-1 mammary xenograft, P388
leukemia, KB, and L1210 leukemia.
22. The cell culture of claim 17 further defined as
producing an amount of taxol that is at least about 1-2
fold increased above that produced by direct extraction
from stems, leaves and bark of Taxus media cv. Hicksii.
23. The cell line of claim 17 further comprising at
least one mutation which confers on the cell a phenotype
wherein the compound is overproduced compared to the non-
mutated cell culture.
24. A method of regenerating plants from cultures
of Taxus, said method comprising:
(a) producing a cell line according to claim 1;
(b) subculturing the cell line in the light at
a temperature of about 25°C in decreasing
concentrations of hormone-containing media
to induce sheet formation; and
(c) regenerating plants from the sheet-
containing cultures.

-39-
25. A method of producing taxol, said method
comprising:
(a) placing a cell culture derived from Taxus
in a bioreactor;
(b) operating the bioreactor so that taxol is
produced by the cell line and is secreted
into the nutrient medium of the
bioreactor; and
(c) collecting the taxol from the medium,
26. The method of claim 26 wherein the cell culture
is produced according to claim 1.
27. A compound exhibiting microtubule stabilizing
activity, said compound selected from the group consisting
of peaks eluting on an HPLC profile of a cell extract from
a Taxus cell line, said HPLC profiles being produced from
methylene chloride extracts of a phenyl column.
28. The compound of claim 27 wherein the Taxus cell
line comprises CR-1 and the peak selected elutes at 18
minutes.
29. The compound of claim 27 wherein the Taxus cell
line comprises CR-1 and the peak selected elutes at 25
